That makes it a little harder, but I can just view source and hit the
page a couple of times, and I will see that the Action="" in the <FORM>
tag changes and know I have to go back one step to get it. If I have to
I can emulate a person coming in from the home page, walking all the
links to the form, then entering it.
I hit the page that generates the random name.
It returns the random name.
I use it in my following request to get the form.
I fill in the form and send it.
Maybe you can make it 'not worth the effort' for a hacker, but be
careful you don't make it 'not worth the errort' for your legitimate
visitors.
The big problem you have, is if I can fill it in by hand, I can watch
what passes over the network and write a program to emulate it. What a
browser can do is very limited, and even things like headers that are
not normaly visible when you view source are visible to a network
sniffer.

I suggest it is time to take a look at sessions:
http://www.php.net/manual/en/html/ref.session.html
Things get easier if you only allow a small group of people into the
site. You won't be able to keep someone who knows a valid username and
password from exploiting things, but you can limit the possible exploits
to what you allow a user to do.
I suggest you use a SSL secured server any time you are sending
passwords across the net. That way they can only be intercepted by
someone with access to the authorized user's machine, or someone with
access to your machine. SSL is not magic, all it does is prevent
someone along the way from snooping.
When someone enters a valid username and password, create a session and
store all the temporary data on the server. If it is never sent to the
browser, there is no way for someone on the other end to modify it. A
PHP session ID is a reasonably secure random number that is hard to
guess. It is even harder to guess the session ID, user name and
password all at the same time.
That still does not stop me, a valid user who can use the system from a
browser, from being able to write a script that fakes my user action.
It does allow you much more control to make sure that neither me or my
robot are able to do anything you don't want me to do.

Hi,
How about the following:
1. Assign a session id to the form every time you generate it.
2. Maintain that session id on the server side in a sort of cache for a
specific amount of time (say, T) only. Time-out and delete session id
entries that haven't been used within time period T.
3. Have the form page refresh itself every T minutes/seconds etc. (for the
convenience[1] of a genuine user).
4. Ensure that a form with a particular session id can be submitted only
once.
1. Deleting the session id from the session id cache the first time a
form is submitted should ensure this. This would lead to the concept
of "using up" or "consuming" a session id.
5. Don't process any form that doesn't have a corresponding valid session id
stored in the session id cache.
While the approach I have outlined above will be susceptible to eavesdropping
(session ids can be sniffed out), that can easily be taken care of by sending
out the form over an HTTPS session.
Of course, if the attacker sets up a robot to request forms from the actual
server and then keeps on submitting spurious data, you're in trouble. There's
very little that can be done against an attack of this sort. You could perhaps
try to keep track of the time difference between the serving of the form and
its submission. This too, is open to subversion.
Please do point out any loopholes you find in the approach mentioned above.
------------------------
[1]
If a "genuine" user stops to do something else after partially
filling out the form, then this setup could become a nuisance.

And it would prevent people who don't sent Referrer headers from using

It's probably a good idea to stop using hidden form fields. Save your state
data securely, use sessions etc.
Then you only have the usual problem of validating the data you wanted the
user to send you , instead of also the hidden data you were hoping they
would leave alone!

Well, anything you get back from the client will be as GET variables, I
think. So, if your forms only use POST variables, and you've turned on
track_vars, then you can get your variables through $HTTP_POST_VARS()
like $foo=$HTTP_POST_VARS('foo'); If I'm wrong on this, I'm sure
someone will let me know.

Well, if there is a GET and a POST variable of the same name,
the POST value will be used instead. This is a built in security
measure of either PHP, Apache or both.
However, what you suggest does not prevent someone from
viewing and saving the source to their machine, modify the
form variables and submit the version of the form on their local
machine. Doing this will set everything as a POST and will
bypass the check suggested above.
This goes back to what I said initially. I can check to see if
the REQUEST_METHOD is POST and check the HTTP_REFERER
to see if it is from our host (which it wouldn't be if the user
submitted the form from their local machine. However, the
problem arises in that the HTTP_REFERER isn't always set
because some browsers do not send that information to the
server.
So this leads me to the (another) question I had, but am not
sure anyone said, at what time and/or in what instances and/or
what browsers/versions do not send the HTTP_REFERER
information?
I really appreciate all the help and information everyone has
given with regards to this issue. You guys are great.

That won't work. Clicking on a link does not trigger sending of fields
(hidden or not).
There are only three places you can pass data without using forms, and
using buttons, or images to trigger a POST of the data.
1. Get parameters after a ?
2. Cookies.
3. In the URL itself.
Why do you want to eliminate all get params and cookies? That might
have a lot of control as to what the best approach will be.

No? How about:
<form name=myForm method=post action=...>
<input bla bla bla...>
</form>
<a href="javascript:document.myForm.submit();">Click here</a>
<a href="#" onclick="document.myForm.submit();return false;">or here</a>

Did you read his previous comments? He *is planning to pass the info in a
form, one for each link...

It is "--enable-trans-sid" and it is turned on. However, the
problem is that it doesn't work. :( If the user does not have
cookies turned on, the SID will not be sent through to the next
page on HREFs (I know you have to do it manually when using
the header() function, but it should be automatically appended
when using HRREFs, but it's not. :( )

A little checklist:
Have you:
- checked the INI file setting "url_rewriter.tags"? With the default
installation this is empty, the needed contents are on a comment line.
The line should read
url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=fakeentry"
Are you:
- explicitly starting a session with session_start() ?
if not, try to explicitly start it
- receiving an (old or outdated) PHPSESSID cookie from the browser?
Maybe Php decides it's not necessary to rewrite the URLs

GET because they can be modified and Cookies because not all users
will have them turned on.

This would require a form for every link and that was something I
illustrated earlier as one of the possibilities I had come up with. But
it was a possibility that I was trying to avoid...

No, you could do following:
<a
href="javascript:document.myForm.action='theLink';document.myForm.submit();">Click
here</a>
...for each link. And you'd have one single form.
BTW. In you first email you wrote: "plan they are pushing is to make our
site(s) free of all GET variables".
Who are "they"?

It couldn't be that generic because as I pointed out in my initial email,
each link can have a variable number of GET variables and not all of
them would have the same name (though, some would).

Then you'd have to insert hidden fields for all possible variables in
the form.

I bet they have nothing better to do than to say: "What are those funny
characters next to the internet address? We don't like them. They don't
let our site look seriously. And we _are_ a very serious company. They
must diappear right away!!"

This still is not working and *any* help at all on how I can get it
working would be greatly apprecaited!!

Here is some sample code I am using. All I am doing
here is to test to see if the SESSID is being passed on
the URL when an HREF is clicked when the browser
has cookies turned OFF. If cookies are turned on, using
this same code, I'll get the same session ID reported
every time. But with cookies turned off, I get different
session IDs every time.
Page1:
<script language="php">
session_start();
echo "Your session ID is : " . session_id() . "<br><br>\n";
echo "<a href=\"page2.php\">Page 2</a><br>\n";
</script>
Page2:
<script language="php">
session_start();
echo "Your session ID is : " . session_id() . "<br><br>\n";
echo "<a href=\"page1.php\">Page 1</a><br>\n";
</script>
Any insight into my problem would be greatly apprecaited.

I'm writing download counter application. I would like to add a speciall
functio0nality that determines wheater download was sucess or not. The only one
solution how to do it I found is PHP's connection handling.
I'm getting connection status via connection_status() function which is call in
function that have been registred as ahutdown function:
function mail_status()
{
mail("[EMAIL PROTECTED]", "connection", connection_status());
}
register_shutdown_function("mail_status");
Then I send header that tell browser to establish download:
header("Content-Type: application/zip");
And then I'm trying to send output which i read from DB(size of 10KB):
echo $content;
All works well, but when i hit cancel button in download dialog window status is
NORMAL and not ABORTED.
When i put this instead of line before it returns ABORTED.
for($i=0;$i<10000;$i++){ echo $i; };
So ... how could I recognize if Cancel button was pressed in download dialog window ???

I am gettign to frips with MySQL, and Basic PHP seems to be sticking in my
brain, but I'd really appreciate it if you guys could point me in the direction
of a good on-line tutorial that'd point out the basics of geting these two
technologies to talk to one another.
Ultimatly, I'd like to have a login screen, that checkes user name against

Hey,
There are a million different sites that have hordes of information to

I'm concepting a system in php that offers user level password protected
upload / download of image files - certain users would only be able to
access certain files.
The file sizes could be anywhere from 1mb on up to 25mb.
I am thinking of storing the (user uploaded and downloadable) files outside
of the www directory (if that is possible with php) and using mysql to track
files and associate them with users. I would like to pose a few questions:
1. How would you get around scrip timeouts on huge 25mb files.
1a. In a virtually hosted situation, how much php can a server
provide if 5 people are tying up connections/php with 25mb downloads.
2. If it is possible to upload files outside of the www directory via php,
would this bring added security concerns to the site. I don't wan't the
files to be browseable by J.Q. Public.
3. Is there a better solution using straight ftp connections that could
also provides user level password protection - keeping in mind that users
would need the capacity to create an account and upload a file without an
administrator having to create directories and passwords.
Thanks in advance for any ideas/opinions/etc.

What is your DB, are you using MS-SQL Server? If it is Developer Edition, I
believe it allows only 1 db connection. (Has MS changed this restriction?
Number of connections developer edition can accept may wrong. I don't
remember well. Correct me if it is wrong.) Or didn't you setup DB to accept
only 1 connection? Sounds like this is the reason to me.

FYI
You might want to add headers using header() with readfile().
PHP does not parse with readfile(), so it is more efficient. i.e. PHP does
not look for <?php ?>.
(I use include() always, though)

How do you determine if the click is the first time, when user send form,
decide to go back to previous page using browser's back button? It's
impossible to determine the click is the first or not using JavaScript.
(It's only works browser does not send form data immediately and it allow
users to send form data while it is sending form data or waiting response
from server. Is this what you want to prevent? Then it works.)
John's uses hash to compare posted values are the same as in DB, it works.
In many cases, it may be a preferred way. If you are just worried about
sending form data multiple times using browser's back button, you can do as
follows using session var.
switch ($task) {
case 'update':
if ($HTTP_SESSION_VAR['FORM_DATA_SENT']==false) {
// do update
}
$HTTP_SESSION_VAR['FORM_DATA_SENT'] = true;
break;
case 'show_form':
$HTTP_SESSION_VAR['FORM_DATA_SENT'] = false;
// show form
break;
}

Hi!
File upload doesn't seem to work from Netscape.
It works with Internet Explorer.
In netscape it says Network Error Occured..
Why's that..?
Thanl You!

Hey there foo::bar($baz) how are you doing?

foo::bar is a method that returns the name of $baz. I can't seem to get
that to interpolate properly. It would make my life cleaner and easier
if this could work. Is this at all possible?
Hi All,
I would like too keep a session going from between 1 to 3 days user

If i change the php.ini then the session will not be changeable how can I do
it without changing the lifetime variable?

You can only request a new page. Period.
PHP runs on the server, button clicks are evaluated on the client
(browser).

String.
This is what I've come up with and it seems to work pretty ok.
What do you guys think?
(test code to illustrate a point; other than the XORing, not
what I'm actually going to do with the "live" code)
<script language="php">
$uniqueArray = array();
for( $i = 0; $i <= 100; $i++ ) {
$certnum = date( "U" ); // what the second variable is always set
to
if( $certnum == $lastCertNum ) {
sleep( 1 );
}
$uid = ( $uid == "nsa000" ) ? "mdb000" : "nsa000"; // sample first
variable
$uniqueNum = ( hexdec( $uid ) ^ $certnum );
echo "$uid ^ $certnum = $uniqueNum<br>\n";
if( in_array( $uniqueNum, $uniqueArray )) {
echo "Not a unique number!<br><br>\n";
}
$uniqueArray[] = $uniqueNum;
flush();
$lastCertNum = $certnum;
}

Depends on what errors you get. "I can't create or manipulate jpegs"
isn't particularly helpful...

OK, it returns a broken image and when I download that the resulting file
reads "ImageJpeg: No JPG support in this PHP build". But tech support says
they installed the jpeg support and that they did it correctly.
I've tried using code that Rasmus wrote, too. And that definitely should
work. :)

I was curious, so I made simple test code, it seems works fine for PHP4.0.4
as Apache 1.3.17 module running under RedHat Linux 7.0.1. (Besides, I have
very similar code that you have. It works for me)
What is your environment?
If you are 100% sure that you don't have bug in code, I suggest to fill bug

Hi,
Imagine the following script:
<HTML>
<TITLE>Some Title</TITLE>
<BODY>
<?php
$var = 1;
if ($var == 1) {
die ("I'm dead");
}
echo "I'm alive";
?>
</BODY>
</HTML>
If I try to execute via Internet Explorer ("5.x") apparently every thing
works fine.
It shows the string "I'm dead".
But if I use the Netscape 4.7x, I get a blank screen.
When I view the Source Code ("HTML code in Netscape") it shows:
<HTML>
<TITLE>Some Title</TITLE>
<BODY>
I'm dead
Netscape can't render the page if its missing the </BODY> and </HTML>
tags in the end.
I already used 'return' end 'exit' functions but with the same result.
There is some configuration parameter to the PHP server to send the rest
of HTML code after exit the script or workaround?
Thanks,
Don't use die (die just stops everything, nothing else gets send).

Is it an option to just move the code below the </html> tag? Another
option would be to echo the closing tags from within the conditional, prior
to calling the die(). I believe output buffering can also be used to
achieve what you want, but someone else will have to explain how (whether?)
that can be done here.

I'm sure there are more officially correct ways of doing it, but I've always
echoed /body /html before the die happens.

I already thought that, but if I want to use the die function inside another
function that can be called anywhere in the script (inside a table or form) I've
possibly the same problem.

That a good idea, I thinks it is a new feature of PHP 4.0.

Subject: can't start apache
Hi
I just installed mysql, apache and php4 on Linux Mandrake 7.0 from a cd I got with the
book "PHP Fast and Easy" After installing apache it seemed ok and started normally.
But after installing PHP4 I get the following error message when I try to start apache:
Syntax error on line 207 of httpd. config: cannot load
/usr/apache_1.3.12/libexec/libphp4.so into server:
/usr/loca/apache_1.3.12/libexec/libphp4.so: undefined symbol: mysql_init
I used the following command to build php4:
./configure --with-mysql=/usr/local/mysql-3.22.32-pc-linux-gnu-i686/
--with-apxs=/usr/local/apache_1.3.12/bin/apxs
Including ./configure --activate-module=src/modules/modules/p in installation fails,
saying directories do not exist. Looking at previous output it appears that the
modules have already been activated.
Any hints in a newbie-friendly format would be greatly appreciated.
Thanks,

Hello everybody,
I am fairly new to php and have the following problem:
I wrote an application that uses sessionhandling. I will enclose parts
of the code below.
It runs fine under Netscape 4.74, or Explorer 5 and also under other
Browsers.
Problems arise under Netscape 4.6 when cookies are not allowed.
When I ask for the startpage, only one of three parts of a frame
appears, and disappears again,
and another part of the frame is briefly displayed and disappears again.
It keeps flickering and doesnt stop.
I have also seen a browser where it was flickering a few seconds but
then finally the
page was properly displayed. I thought that was because PHP seems to set
cookies, but if that doesnt
work it uses its own sessionmanagement.
Something seems to go wrong in our case.
My boss thinks our problem has something to do with cookies,
as it runs fine as long as cookies are enabled. It also runs fine if we
order it via https (SSL).
Do you have any clue what could go wrong and how I could try to fix
it???
Why does it work with SSL?
I hope I have been precisely enough in describing my problem. I tried as
hard as I could ;-)
If not please ask for more information.
Thank you very much for your help!!!!!
Here is part of the code:
The following function is called on top of every page that I wrote by
<?php
top_of_page(getenv("SCRIPT_FILENAME"));
?>

Greetings, all.
I'm a relative newcomer to PHP, looking into the possibilities of setting up
a LAMP (Linux, Apache, MySQL, PHP, and Perl) platform for a new web server.
We have everything set up and running currently, with PHP 4.04 running as an
Apache module. We'd like to pitch this to the higher-ups as a good thing
for our site and our customers (who would also be able to use PHP), but we
first have to address some security concerns.
Namely, we're thinking it would be nice for users to be able to write
scripts which would generate and store files within their home directories.
However, because PHP runs as nobody, any such file would essentially need
writable permission for every user. This leaves any PHP-written file
vulnerable to exploitation by anybody with a site on the server and some
knowledge of PHP.
Essentially, I'm wondering if there's any way in this situation for a PHP
script to inherit the permissions of the user that owns it. This would
allow us (and our users) to write freely within the confines of our own
directories. Nice thought, but I'm really beginning to wonder if it's
doable.
Any input or suggestions which could be offered would be very much
appreciated. Thanks.
Does anyone know how to fix the following problem? I have configured php
with --with-pfpro=/usr/local and it does not complain about the header or
the library.
root@server5:/usr/local/apache/conf# ../bin/apachectl configtest
Syntax error on line 213 of /usr/local/apache1317/conf/httpd.conf:

I have run into this before with other undefined symbols but have just
reconfigured php to included the library. Any ideas?
-Bob
When I try compile php I get the following error that is directly related to
PNVersion:
root@server5:/usr/local/phpApache/php-4.0.4pl1# make > make.out
pfpro.c: In function `php_if_pfpro_version':
pfpro.c:129: warning: initialization makes pointer from integer without a

root@server5:/usr/local/phpApache/php-4.0.4pl1#
The code in pfpro.c that is affected is:
/* {{{ proto string pfpro_version()

PHP_FUNCTION(pfpro_version)
{
if (ZEND_NUM_ARGS() != 0) {
WRONG_PARAM_COUNT;
}

}
Is it just a coincidence that this is bombing out as well as the undefined
symbol...

Hello!
I'm facing a problem.
Inside of a php3 script - I have a string that contains html code as well
as php3 code.
At start, when I tried ECHOing the string to screen, the php commands
weren't activated
and viewing the source of the generated page allowed me to see that they
were just left
as they are, without any compilation.
How can I make those php3 commands to work as they supposed to?
Thank you in advance -

Take a look at the eval() function

It does exactly what you are looking for...

Actually it doesn't. My string does not(!!) contains only php code.
It contains HTML tags, text, and php code (called with <?php ?>).
Now, What should I do in order to run both the html tags and the php commands
in it?

I don't know any real function that does it...others could know
something more about this, but if nothing is presented to you, you could
do something like:
- get all the '<?php' '?>' tags' position and separe them from the
other code (that will be HTML);
- you will have two things (could be an array of data). One is all the
php code and the other is the HTML code; If you create a bidimensional
array you can create a sequence of php and html code, or better than
that, create a vector that will have the Data Type (HTML or PHP) and the
value (the code)
- Then, for each row or field of you array/vector , you check if it is
php code (then use eval) or HTML (then use echo).
Hope this helps,

hi all, just a quick question.
i've made a personal addressbook, the code for which i'm going to
release soon (best probably for newbies). anyway, i want to make it
so that i can pass multiple email address from one page to another.
basically it'll be a form select function like :
<select name="$emailto[]";>
<option name="email1">name1
<option name="email2">name2
<option name="email3">name3
<option name="email4">name4
</select>
now say i select name 1 and 4. i want to extract the emails on the
page the variables are passed to, seperated by a comma.
any piece of code??
thanks!

Php is not parsing .data files, I have the following in Apache config.
AddType application/x-httpd-php phtml php php3 data
Thanks,
David
Try putting this in your config in place of what you currently have:
AddType application/x-httpd-php phtml
AddType application/x-httpd-php php
AddType application/x-httpd-php php3
AddType application/x-httpd-php data
Then restart Apache and see if that does it for you.

I don't like stored procedures, or functions in any programming language that
accepts many parameters, and I avoid the as much as I can. Those things are
hard to debug and write (hmm, what paraemeters should go here ? :-( ) and
they hinder the readability of the code.
As for null values, I don't use them as well, I work with different databases
and each one has their quirks about null. Basiclly null is undefined and
should stay that way. Usually I decide on an invalid value (such as -1) and
pass it to the function.

Well I can do all of this in mysql because there's no referential integrity.
You can't drop or modify a column which is reference by a foreign key,
beacuse that would break the integrity. You don't need to rebuld the table,
just drop the foriegn key and off you go.

Well let me see,
1. I have several databases to choose from, Which give me the performance I
need.
2. I don't have to be a DBA to manage them, I don't have to use raids to get
performance and I don't have to split indexes between hard disks to get
adaquete preformence.
3. I don't a supercomputer and I can use them in moderate hardware for my
needs, and I don't have to dedicate plenty of RAM to them.
4. This databases are open-source and don't have linking problems. Anyone
tried to install Oracle 8.0.5 on Linux (patch-O-rama for Glibc). 8i is a
resource hog (JVM in the database, are they nuts ?) and i won;t touch it with
a stick,
5. I can expect this databases to work for me out of the box (out of the
install in this case)
6. All this databases are free and I can choose the one I want according to
the task I'm facing, without paying outrages licensing fee to Oracle, and
spending lots of money on unnedded hardware.
Isn't the choice obvious ? Why would anyone touch Oracle - I guess it is only
because of their hype and spin - much like some other company I won't mention.
BTW, I was in Oracle's OPP program for quite a while, but left it when 8i
came out, it was an overkill. (But I sure miss those Oracle parties, They
were outrages, or as one of their representives said to me, they had lots of
money the needed to spend).
OK, I'll stop now, I'm running out of air, I think I'm turning blue, Help !!
Help !! someone ? anyo.... ahhhhhhhhhh ^^^_^^_^___________________

Well, I'm building this site for a shop. It's audience will probably be
adults between ages
of 25 to 55. They won't be Internet wizards, but this shop is rather
expensive so they will
probably be more than just common people.

hmmmm..... I'm getting tired from this Hebrew issue.. This is probably the

Still no quick answers.. you chose to ignore Visual-Only browsers.
You told me that many Hebrew website developers didn't.
What should I do??

Does anyone know if there exist an job-ad script?

I have a problem with the session not using cookies.
The code below doesn΄t seem to set a cookie even though my php.ini has it
set.
If I use the header after initializing the session, nothing appears in
getsess.php.
If I click the link on the other hand, the PHPSESSID-variable is added to
the URL.
What do I do to enable the cookies?
(I know how ordinary cookies work and how to set and delete them=
<?
// -- default.php -->
if ($submit) {
$pref_username = "tobias";
$pref_password = "password";
if ($pref_username == $username && $pref_password == $password) {
session_start();
session_register("SESSION");
$SESSION["username"] = $username;
$SESSION["password"] = $password;
// header("Location: getsess.php");
// echo "<a href=getsess.php>go</a>";
} else {
header("Location: $PHP_SELF?username=$username");
}
}

Hmmm. So, I try to recompile to reproduce the error, this time advancing
back to .12; I compile; no errors AND the module error goes away (thus,
it works great as it always had on RH6.2).
Weird.
These are the only two things I can think of.
My progression was this; get .12 (it failed to compile; (php+apache -
pspell/aspell compiled fine), read php-dev, saw there might be issues so I
reverted back to .11.2 (pspell). It compiled, but, with the aspell module
issue. Figured perhaps it was the most recent aspell (I had gotten
aspell-.33); so, I reverted that back to 32.6; recompiled still got aspell
module issues. Noted that RH7 have some glibc issues (and, it had caused
some other issues with aspell/pspell); updated both glibc and gcc from
redhat (rpm updates), recompiled, still had aspell module issues with PHP.
Finally, to replicate the compile error I went BACK to pspell .12,
recompiled, everything worked.
So, the two things I can think of is:
a) the newest aspell libraries are causing problems either in the compile
or in the aspell module loading
b) redhat's buggy glibc/gcc
the only odd thing was that I can't necessarily isolate either of these as
the cause. But, aspell 32.6+pspell .12+updated RH glibc 2.2-12 &
gcc-2.96-69 + apache 1.3.14 + php-4.0.4pl1 works on RH 7 now. My
inclination is that it's aspell, since, the same behavior existed with
both stock and updated glibc and gcc.

Hi.. We have a city map using co-ordinates to link to specific info on various
buildings, etc. The links bring up an information page with data and photos for
each building locations on the map.
My question is, when this information page is accessed from another direction,
say a menu, can there be a link that operates in 'reverse', back to the map and
the building in question? We still want people to see the map, relating to a
specific building, whether they start there or end up there.
I thought the map could perhaps position itself so that the point of interest is
always in the center, or that it blinks, or has a arrow pointing to it. It
doesn't matter what the final display looks like, just that is shows a
particular location clearly.
Can anyone say if this is even possible?
Thanks.
Floyd

Hey Floyd,
You can do lots with dynamic info using gd and PHP's image functions...
for example, you could read the map into a new image, draw a circle
around the area in question, then output this new picture...check out
php.net's info on images:
http://www.php.net/manual/en/ref.image.php
best of luck,

I have a string that can be any length and contain any
number or words. Each string also has, somewhere
near end, a list of parameters that can begin with any
number of five or six different parameter markers. I
need to find the position of the first of these
parameters markers, which can be in any order, so I
can seperate the user string from the parameters...and
I can't change the way the information is provided.
The only way I could get this to work is, since
there's only five different markers, locate the
position of each marker in the string, stick it in an
array, sort the array and find the first element that
is greater than 3 (the strpos uses an offset of 3
since the user portion of the string cannot be less
than three charcters long plus a space), this element
has to be the marker and position that begins the
parameter portion of the string.
Anyone know of a better more elegant ( read as faster)
way to handle this problem.

This is driving me nuts. I really tried to figure it out
myself. I have a form for creating a table. The form
fields have field_name field_type field_length, and
checkboxes for not_null, auto_increment and primary.
When I check the primary key checkbox it always makes
the first field the primary key no matter what. And it
makes two date fields I enter NULL and the rest NOT
NULL no matter what I put in the checkboxes. The code
is below along with a printout of the SQL query. I only
wanted suffix and death date to be null. This is combination
from PHP Fast and Easy and MySQL by Dubois.
$sql = "CREATE TABLE $table_name (";
for ($i = 0; $i < count($field_name); $i++) {
$sql .= "$field_name[$i] $field_type[$i]";
if ($not_null[$i] == "Y") {
$additional = " NOT NULL";
} else {
$additional = " NULL";
}
if ($auto_increment[$i] == "Y") {
$additional .= " AUTO_INCREMENT";
} else {
$additional .= "";
}
if ($primary[$i] == "Y") {
$additional .= " primary key";
} else {
$additional .= "";
}
if ($field_length[$i] != "") {
$sql .= "($field_length[$i]) $additional,";
} else {
$sql .= " $additional,";
}
}
$sql = substr($sql, 0, -1);
$sql .= ")";
