You need to get an additional IP address from your hosting provider (if you use one) and then configure the box to act as a nameserver. I did just this for becomingdigital.com, but strangely it had nothing to do with PHP.

[PHP] [Newbie Guide] For the benefit of new members
= This message is for the benefit of new subscribers and those new to PHP. Those who do not want to be bothered just filter out the [Newbie Guide] mails. Please feel free to add more points and send to the list. == 1. If you have any queries/problems about PHP try http://www.php.net/manual/en first. You can download a copy and use it offline also. 2. If you can not get answer here try http://www.google.com next. Try searching for "php YOUR QUERY" and you may be lucky to get an answer within the first 10 results. 3. Glancing through the list archive at http://marc.theaimsgroup.com/?l=php-general , you can find many of the common topics discussed repeatedly and can get your answer from those discussions. 4. If you are stuck with a script and do not understand what is wrong, instead of posting the whole script, try doing some research yourself. One useful trick is to print the variable/sql query using print or echo command and check whether you get what you expected. After diagnosing the problem, send the details of your efforts (following steps 1, 2 & 3) and ask for help. 5. Provide a clear descriptive subject line. Avoid general subjects like "Help!!", "A Question" etc. Especially avoid blank subjects. 6. When you want to start a new topic, open a new mail and enter the mailing list address [EMAIL PROTECTED] instead of replying to an existing thread and replacing the subject and body with your message. 7. PHP is a server side scripting language. Whatever processing PHP does takes place BEFORE the output reaches the client. Therefore, it is not possible to access the users' computer related information (OS, screen size etc) using PHP. You need to go for JavaScript and ask the question in a JavaScript list. 8. It's always a good idea to post back to the list once you've solved your problem. People usually add [SOLVED] to the subject line of their email when posting solutions. By posting your solution you're helping the next person (please refer #3 above) with the same question. [contribued by Chris W Parker] 9.

Re: [PHP] remove spaces using php function
You mean something like
ereg_replace(' +', ' ', 'asked his friend..');
or perhaps
preg_replace('/ +/', ' ', 'asked his friend..');
?
Of course, if you're getting this data from a luser, those may not be spaces.
They could be obscure, non-printing characters. Take a look at bin2hex to
find out.

[PHP] set_time_limit() on Mac
i gotta wierd one, maybe it's just me being daft...
i'm under the impression that max execution time / set_time_limit() is
server specific, and completely independant of what computer is being served
the pages?
my server is apache 1.3 running php 4.3 on win 2k...
when i run the script from a windows machine, it runs fine. my line that
does a set_time_limit(10) works and the script happily runs for about 2
minutes while a loop does some file copying (across the network to the
server, and independant of whatever machine called the script).
however, if i run the same script from my little iMac (shudders) then it'll
give me a script timeout saying it's gone over the max execution time of 10.
now i know that set_time_limit(10) is being run, as the server default is
30. it just doesn't seem to be resetting this value in the PHP loop. but
surely that's impossible, as it should be all server side?
secondly, i have a timer that (using javascript) writes to the html page how
long the script has been running, and an estimate of how long is left to
run. again, perfect timing on the PC, but when run from the Mac, the timer
counts 1 second roughly every 2 seconds. again, surely this is impossible as
time functions are run from the server???
the other strange thing, if i have the script running off a PC, and the Mac
then also runs it, it'll time perfectly... it'll still time out, but it'll
atleast count proper seconds...
here's a rough idea of the code... i've cut out most of the crap that it
does to give you an idea of what's happening, ignore any syntax errors, as
the script does work... the flush() works nicely to update my form fields
with javascript so i can see the live results of the script working... and
see the problems with how mac seems to be handling it.
anyway, any ideas would be very appreciated, as i don't want to have to
fudge it and stick set_time_limit(1000) at the beginning of the page :(

[PHP] function call before declaration
Hi!
I got a problem with functions which I call before they're
defined. I get the error message:
Fatal error: Call to undefined function: view() in
/daten/www/midgard/cache/62.php on line 470
The code snippet:
8<-
switch($argv[0]) {
case 'view':
view((int)$argv[1]);
break;
default:
view();
break;
}
//
function view($mgd_eid = 0) {
global $self, $eventtypes;
if($mgd_eid) {
if(!$event = mgd_get_event($mgd_eid))
die("Ungültige Event-ID");
$start = date("
...
8<-
It worked before (Suse 7.2 php 4.2.0) and now
it won't (Debian Woody php 4.1.2) I reckon it should
work since php4. Perhaps a misconfiguration? The functions
are not conditionally defined!
Any Ideas? Thanks in advance!

[snip] i'm under the impression that max execution time / set_time_limit() is server specific, and completely independant of what computer is being served the pages? [/snip] Not server specific and overrides whatever you have set in php.ini and httpd.conf for the page in which the set_time_limit is contained. set_time_limit(10) limits the script to 10 seconds. [quote] When called, set_time_limit() restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out. [/quote] So your script is running for a certain length of time, then it hits the set_time_limit function and quits after 10 more seconds.

After the processing the page is redisplayed - but the data originally sent persits (in the request) this can be a pain if the user was to hit the refresh button then the data is submitted to the server again and if for example the php page does an insert into a database then a new row would be created etc... Is this normal behaviour of php and jsp ? I am not sure but I am noticing it now with php ? Should I be clearing the data from the request somehow after I have done my processing?

I changed some map names and i also edited some .php files, i added 'set_include_path' in some .php files. When i open test.php i see that it reads the ini file, and it also reads the forumbuilder.php, but it stops here (used print function): // Initialize array with default values $formValues = $this->_do->toArray(); What could be the reason that it stops at the above line or in the called method.

Re: [PHP] New to PHP form attributes
You should use post method for forms that change state on the server,
that way the user gets a warning. And you should redirect after
processing the form to another page.
if($_GET['action']=='submit') {
INSERT INTO table VALUES (NULL, '$_GET[input]'
header('Location: ...');
} else {
}

can be a pain if the user was to hit the refresh button then the data is
submitted to the server again and if for example the php page does an

Is this normal behaviour of php and jsp ? I am not sure but I am
noticing it now with php ? Should I be clearing the data from the
request somehow after I have done my processing?

[PHP] Going crazy-db3
I have been trying for over a week to write to the sendmail aliases db3 file and have been unable to do so regardless of how I configure the arguments with the dba_open statement. It keeps telling me "Invalid argument". It works fine within BerkeleyDB. I can read the file just fine but cannot open it in write mode. Also, phpinfo and dba_handlers both show that db3 is available as would be expected if I can read the file. When I do a db3_verify and db3_stat from a shell on the test db they both come back just fine. Any help would be great as I don't want to rewrite everything in perl. -Bob Here are the warnings I keep getting: PHP Warning: dba_open(aliases5.db,w): Driver initialization failed for handler: db3: Invalid argument in /usr/local/www/data/maillists/test2.php on line 2 Here is my test code, it always displays "dba_open failed" and if I take out the check for an open handle it obviously bombs. I have tried it with "wl" and many other combos. No luck: Key: " . $key .

Re: [PHP] php&javascript live-clock
At 15:48 7-10-03, you wrote: hello, is it possible to show the live-clock from the server machine, using php and javascript, without having to make refresh of that page? That would be a 99% javascript job. Find an existing javascript that works. When the page is loaded let PHP feed the javascript with the current servertime. In javascript immediately read the time on the usersystem. Option 1) Compare times and recalculate Calculate the time difference and remember that. At every time the time has to be displayed again, use the calculate time difference to adjust the time you read on the PC to servertime. Option 2) trust counters I'm sure there are time counters in javascript. Start one when the page is loaded and to display time add them up. For both options you will need functions to add times, this is tricky at the end of the hour and at the end of the day. (and keep in mind the time difference can be positive as well as negative. good luck.

[PHP] Modifying OPTIONS header response
Hello all, I'm working on a php/dav server and I'm having a problem. When the client sends an OPTIONS request to see what methods are allowed, they only get "Allow: GET, HEAD, POST, OPTIONS, TRACE" back from apache. This seems to me a problem since it does not include PROPFIND, COPY, MOVE, LOCK, etc. and some clients don't even try to lock the file and open it read only, I guess because they don't see LOCK, etc. as allowed. My question is, how can I modify the OPTIONS response or at least the Allowed methods?. I can capture/handle HEADs, GETs and everything fine but OPTIONS does not seem to work. Any hints?.

AFAIK, no. PHP scripts get their time information from the server. JavaScript can get its time from the server or the client, but it counts the time on the client side. If your web browser counts time a bit more slowly or quickly than the server, the time drift would result in your JavaScript clock to become more inaccurate over time. Then you would have to refresh the PHP page and re-sync your JavaScript clock with the server. This is not be a big problem if your time drift is "minimal" and your intervals between page refreshes is "reasonable". -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

[PHP] allowing access to php page by IP
Hello,
I want to allow access to a php page but am not sure how I should verify
the IP once I get it. I want to allow 10.8.4.* and 10.8.5.* to access a
certain webpage and keep everyone else out. I have written code to figure
out what someone's IP is, but am not sure about how I should verify
whether the IP is in the range of 10.8.4.* or 10.8.5.*. Any suggestions?
I was thinking of either using a regex (but I dunno regex so I'd have to
learn it) to stip off the .* octect and then compare the rest of the IP
and see if its either 10.8.4 or 10.8.5, or create a for loop and loop
through 1-254 and cat it to the end of 10.8.4. and 10.8.5. and compare it
to the IP they are coming from. Any suggestions on how I should do it?
Here is the code I have to get the IP:
if (getenv("HTTP_CLIENT_IP"))
{
$ip = getenv("HTTP_CLIENT_IP");
}
elseif (getenv("HTTP_X_FORWARDED_FOR"))
{
$ip = getenv("HTTP_X_FORWARDED_FOR");
}
elseif (getenv("REMOTE_ADDR"))
{
$ip = getenv("REMOTE_ADDR");
}
else $ip = "UNKNOWN";

Convert the ip numbers to integers and check if the incoming ip is within range.
You can use ip2long();

Yes, bit basic but it should work. substr().
www.php.net/substr
$FirstPartIp = substr($ip,0,5);
if($FirstPartIp=='10.8.4' || $FirstPartIp=='10.8.5'){
echo 'We have a local IP, continue!';
}else{
echo 'Get out stupid hacker';}
Should work. An other way is exploding the IP by .
www.php.net/explode
$IpParts = explode('.',$ip);
$IpParts is now an array and you can check for the correct address.
Good luck,

You need to be more specific here. After the processing, the page is
redisplayed? Does this mean you simply generate the appropriate output (using
include() perhaps), redirect the user somewhere, the user clicks reload, or
what? I would assume the first, but your problem sounds like you are doing
something else.

Now this question comes up a lot. There are many ways around it, and you will
probably find more than I can mention by searching the archives. In fact, I'll
only give you one suggestion now.
If you form, form.php, submits to process.php, you can process the form with
process.php and then include a Location header that redirects the user back to
form.php:
header('Location: http://yoursite.org/form.php');
This type of redirection is transparent to history mechanisms, so even clicking
back in the browser won't cause the intermediate page to be displayed. A user
who clicks reload will be reloading the form.php page which only generates the
HTML form.
I recommend searching the archives for other alternatives and choose whichever
one seems best to you.
> Is this normal behaviour of php and jsp?
Yes.
> I am not sure but I am noticing it now with php?
Yes, it seems you are noticing it now, thus your question.
Hope that helps.

Leaving register_globals disabled certainly doesn't force people to "script safe[ly]". It does, however, force them to understand where data is coming from, and that is an important point.

I believe this is because you are using the #! method to define the interpreter, which means your Web server simply executes the script the same as you would from the command line. What you may want to do is to have the Web server interpret .cgi files as PHP, assuming all your CGIs are PHP scripts. Then you can leave out your #! line at the top also. Hope that helps.

It is only an issue in the sense that it hides the origin of data. An attacker can leverage this fact to exploit weaknesses in your application. When a developer uses $_GET['foo'] in his/her code, it is more obvious that the data is tainted than if the developer uses $foo, which could be tainted or could be filtered. It also keeps client data from crossing over, and distinguishing between POST data and GET data can be crucial in defending against attacks such as Cross-Site Request Forgeries (CSRF).

All that it is about that if you have code like this:
if($user=='admin' && $pwd=='secretpassword') {
$admin=true;
}
and register_globals on someone can pass a get (or to have it more
confortable cookie) variable and gain admin access. Sure, you should
initialize all your variables with safe values and you are fine:
$admin=false;
if($user=='admin' && $pwd=='secretpassword') {
$admin=true;
}

The reason why I'm having my php run as a .cgi in the
first place, is because I want the script to inherit
the user/group of the virtual host that it's running
under (using suEXEC), and this is not possible when
using a php script interpreted through the web server.
It must be run as a .cgi, since .cgi's will inherit
the user/group. This is no problem in Perl, since it
provides a way to pass variables from one .cgi to
another (using my $query = new CGI;
param('testbox');). But I can't figure out how to do
this in PHP, since using $_GET['testbox']; always
produces "Undefined index: testbox in test.cgi on line
8".. Thanks,
John
P.S. If anyone has any other ideas of how to get a PHP
script to run as a specific user/group under a Virtual
Host, I'm all ears.. All I need is for the script to
be able to mkdir as a specific user/group, but this is
proving to be more than a small challenge!

Your laziness is causing you problems. Please check out ALL of the
documenation located at http://www.php.net since this is covered under
basic syntax and we don't cater to lazy people (at the very least *I*
don't cater to lazy people).

Directly from the docs:

First line:
"If called from within a function, the return() statement
immediately ends execution of the current function"
Important concept:
IMMEDIATELY returns.

Hey peeps. Let me make this simple.

I expected the array to be created like this: Array ( [0] => Array ( [0] => 2 [c.id] => 3 [1] => 3 [cc.id] => 3 [2] => SDG6004-XX-XXX [cc.prod_id] => SDG6004-XX-XXX [3] => Model 6004 [p.name] => Model 6004 [4] => 89.00 [cc.price] => 89.00 [5] => 2 [cc.qty] => 2 ) ) But alas... that's not how it works.

But yes, that would be a bug probably if indeed the the return expression should never be evaluated due to the left operand evaluating to true. Nonetheless, it's a dirty style for a return IMHO since if the left operand does evaluate to false then the conditional is undefined as far as I can tell.

The code in question, I believe, was basically this:
function foo()
{
true or return('foo');
}
Your answer does not address the question as to why this is invalid syntax, but
instead you explain how return works. This is what Leif is questioning, I
believe.
Regardless, a little less hostility would be nice.

The original post came from someone being lazy, that appears to be
influencing my take on the thread :) Also given the above code, it's
completely pointless since the first operand is true and so it is
impossible for return( 'foo' ) to ever be evaluated (and as stated in a
post just before this the expression shouldn't break). Nonetheless given
a variable as the first operand, I think anyone coding a return in a
conditional like that is asking for trouble since I would guess that it
has an undefined return value.
Cheers,
Rob.

I would say the real issue at hand here is that the return statement is
not a fucntion, but rather a language construct, thus it cannot be used
as a function unless explicitly stated as so. The reason a parse error
is occurring is because this particular construct has no support for
being used in the given context. It would be like dropping in any other
language construct suddenly such as a { or @ where it is not understood.
Given that die() and exit() works just means they have been given
support for this context.
Cheers,
Rob.

Understandable. :-)

I don't think that was the point. You can rewrite it like this if you like:
function foo()
{
false or return 'foo';
}
I believe the original poster mentioned being lazy to justify why this code is
not used instead:
function foo()
{
if (!false)
{
return 'foo';
}
}
The conditional expression itself is irrelevant. This is a question about the
language construct.

Well, anyone who tries that code will get a parse error, so that is definitely
an invitation for trouble. The return value would be defined if this worked as
I think it the original poster indended. The 'or' is not a typical conditional
statement, by the way, otherwise this would work just fine.
Hope that helps.

Sounds to me that if it looks like a function, quacks like a function, etc.,
only a broken language definition would treat it differently from a
function...

Generally it doesn't look like a function since you can do: return 'foo' which has no parenthesis. The parenthesis are optional and only used to return the result of an expression.
