Hi all,
I'm wrestling with this problem for a while now. I want to read a binary
file (created by C software) using PHP. I know of unpack(). But the C struct
that is stored in the binary file contains variables with bitfields:
struct some_struct {
char val_a : 2
int val_b : 7
}
Such a construct means that val_a is char with a bitfield of 2 and therefore
can contain values between 0 (00 binary) and 3 (11 binary). val_b is an
integer with a range of 0 (0000000) to 127 (1111111).
Now the problem is: how on earth do I handle those values with PHP's
unpack()?!? I've tried a lot of syntaxes but none of them seem to work. Can
someone please shortcut whether it is possible or not and if yes, *how*?
Thanks in advance,
Tim

Hi,
I am having some problems with duplicate form input.
I have a form that adds comments to an article, works fine, but if the
user clicks on "refresh", having added a comment previously, the same
comment is added again. I tried clearing the variables after the database
write, but the refresh somehow resends the previous values.
Roughly, heres how my script works: (not using actual code syntax here)
------------------
if {$flag=1 AND $name!='' AND $commentbody!=''){
inserts the comment into the database
$flag = 0
$name = ''
$comment = ''
}
------------------
routine to display the article and the existing comments here
------------------
form here
if user clicks send, puts $flag=1 and calls same page
------------------
How can i prevent these double entries? Some command to definitely clear
the variables?
Thanks.

There is a very simple solution to this on the page that
does the entries into the database simply to a header redirect
to a new page that displays the success notices etc and if they
do a back or a refresh nothing will happen as the POST data
is on the previous now "removed" from history page.
header('Location: http://www.yourdomain.com/success.html');
* you will need to put some GET data in the URL to show the correct page.
That will do it for you.
Remember that you can't send output on the database entry page simple
to the database calls and they do the header call as above.

to a new page that displays the success notices etc and if they

is on the previous now "removed" from history page.
I understand, but the reason i am trying to stick with just one
page is that i want it to be practical. I mean, the moment the user clicks
"submit" the page reloads and shows his comment immediately, and give him
the functionality of pressing refresh to see if anyone else commented in
the meantime.
Also, by using a different page, even with a redirect back to the
original, might take a little while, since the original is a bit heavy on
the download side. ;-)

You can still use one page and use a "middle-man" technique. The part
that processes the form input would redirect back to itself after the
data is inserted into the database, thus getting rid of the post data.
So subsequent refreshes of the page will refresh without attempting to
repost the data.
The only other way to do it is to check the data you're about to insert
to see if it's already there. If it is, then don't insert it...

The redirect using the header method is instant and if the middle
page just does the inserts and you redirect right away using PHP
it is not noticable at all.

I gave up on reinventing the wheel and i am trying to use that
middle-page method you guys mentioned. To make things a little more
transparent to the user, i thought of using a popup window instead, you
know, a tiny window pops up, with the code to insert the comment on the
database, and closes right after it does so.
but err..how can i close it right after the database insert?
Pag
--- End Message ---
--- Begin Message ---
You can close it with JavaScript.
Something like
<script language="JavaScript">
function open_a_window_please(){
lovechild = window.open("childpage.htm");
</script>
Now we have a name that can tell the browser which window to close.
We're ready to use the "window.close()" method. In the parent page add the following
closing link:
<body>
<a href="javascript: open_a_window_please()">Click here to open a window.</a>
<a href="javascript:lovechild.close()">Click here to close the child window.</a>
</body>
Dont forget you will need to use "flush" betwen your major parts otherwise it might
not get sent to the browser right away.
Mike
P.S. Alot of PC's dont allow window.open anymore. People install ad blockers so it
doesn't work.

Hello friends.
Somehow, I cannot find the right code here.
I have a radio group with options as follows:
value1 = orgname
value2=orgcity
value3=orgsize
value4=orghead
When the user chooses "orgname" he must be redirected to the page ../orgname.php
When the user chooses "orgcity" he must be redirected to the page ../orgcity.php
...and so on.
Can you please help me with the code?
Thanks

Say your radio group was named "choice" then you could do something like
this:
Header("Location: http://yourdomain.com/{$_POST['choice']}.php");
Throw in some validation to $_POST['choice'] (or $_GET['choice']) to
make sure you are directing to the directory you should be directing to.

redhat, apache2.0.43 (as dso). compiles and runs without a problem
php4.3.0release fails to utilize php.ini settings. ignores changes to the
ini file.
./configure --with-config-file-path=/usr/local/apache2/conf/php.ini --with-a
pxs2=/usr/local/apache2/bin/apxs --with-mysql (got no errors)
this was not an issue when i had 4.3.0RC2 installed in the exact same
manner!
ive tried this twice, reinstalling apache as well with not difference and
since php otherwise works with its defaults i have a feeling this might be a
bug with the release!?
any help appreciated,
omer.

Hi Everyone,
I have one file with several sections of code which I have so far
accessed using a good old fashioned - - if ($HTTP_GET_VARS['action'] ==
"Update") - - however I now want to include this code within some other
web pages, I thought I may be able to use the following code - -
include("/modules.php?action=Update") - - however the code does not run.
Hoping someone can help me out on a way to overcome this. I am running
IIS 5, and PHP 4.2.3
Thanks
Stephen

When you include() a file, it has the same variable scope as the file it
was included from. So, if you have the following code:
$action = "Update";
include("modules.php");
Then you can use $action in modules.php and it'll be set to "Update".
modules.php will have the same variables as the file that included it.
I hope that helps...

I can't get this to work, I'm using RH 8 with php 4.2.2.
Is there a way to fix this? I think its something to do with ucd-snmp
and me needing to use net-snmp but I'm not sure.
Any ideas?

Can't see anything in the changelog but after upgrading to 4.3.0 I get an error when
using leak();
Fatal error: Call to undefined function: leak() in .........
I was previously using 4.2.3 and it worked fine.
I upgraded with the Windows Binaries (PHP 4.3.0 installer [1,028Kb] - 27 December
2002) and running on Win2k/Apache.
The function still shows as being a function as such..
http://www.php.net/manual/en/function.leak.php
and there is no notices that it won't work with 4.3.0
I can probably run the script without the function fine but has anyone else found any
problems with using this function in 4.3.0 or have I configured something wrong? :P

leak() is only included if you compile PHP with debug mode.
Out of interest, why on earth would someone in user-space be using
the leak() function.

What I have that you do not:
cli - create command line interface executable program.
calendar - fancy tricks with dates.
pear - a library of handy functions
gd-native-ttf
pdflib - create pdf files
ming - create swf files
magic-quotes - eliminates a lot of addslashes()
mm - I'm not sure
pspell - spelling checker
I don't think anything I added would make any difference.
Things that look wrong to me:
--with-low-memory, --with-elf and --with-x are not listed as valid options
in ./configure --help, and look scary to me. Get rid of them.
You used enable-zlib, but the correct statement is with-zlib or with-zlib-dir.
--enable-track-vars - is enabled by default and ignored for a couple of php
versions now.
--enable-versioning - is only needed when you want to run more than one PHP
module version at the same time.
The next thing to try...
xpm-dir, bz2, imap, iconv are the modules you are using that I am
not. Try compiling without them and see what happens.
I don't see where any of these _should_ affect things, but I've gotten in
trouble before using options I did not need...
--prefix - --with-apache specifies where the resulting files are placed, so
prefix is not relevant to static install.
localstatedir, infodir, mandir - not relevant to a static install because a
php module does not use any of the directories specified by these.

I have the following code with a rather odd behaviour:
<html><head><title>Test></title></head><body>
<?php
$string='This is some text which will eventually need
to be split<p>
Hopefully it gets done here</p><p>
I would like that very much</p>
<p>but whether it will happen or not</p>
<p>is difficult to say.</p>';
$Xarray=preg_split('/(?=<p>)/',$string,-1,
'SPLIT_DELIM_CAPTURE');
$count=count($Xarray);
for ($i=0;$i < $count;){
print $Xarray[$i];
//print $i;
$i++;
}
?>
</body></html>
The behaviour is that on the last '<p>' delimiter that
is supposed to be returned instead returns 'p>',
leaving of the first '<'. Below is the source:
<html><head><title>Test></title></head><body>
This is some text which will eventually need to be
split<p>
Hopefully it gets done here</p><p>
I would like that very much</p>
<p>but whether it will happen or not</p>
p>is difficult to say.</p></body></html>
This was done as a test to figure out what was going
on. I am probably making some stupid newbie mistake,
but I have no idea what it is. Any ideas?
Best,
Nik

Ok, I am a bad coder. :( I can't figure this out at all:
$fileID = fopen("nicknames.txt", 'r');
$stuff = fread($fileID, filesize("nicknames.txt")); fclose($fileID);
if (strlen($stuff) > 0) $priorNickNewLine = "\n";
$nicks = explode("\n", $stuff);
The last line produces the Warning.. why? I am trying to read contents from
nicknames.txt and split according to the newline character so that each nickname is an
array element.
What did I do wrong? :(

Hello!
I just want to get the actual date and time which works fine with
date(). The problem is that php doesn't give the european
daylight-saving-time in summer, so the time shown is offset by 1 hour in
summer. It seems that my internet service provider doesn't adjust the
clock of the server to this. How can I avoid this without manually
correct it every spring/autumn?

hi,
Windows XP, Apache 2.0.43(Win32) with PHP 4.3 can't load DLL
'php_domxml.dll'.
it pops-up: Unknown(): unable to load dll'C:\php\extensions\php_domxml.dll'
if I use the old 'php_domxml.dll' from PHP 4.2.4, it works fine. I'm using
libxml2-2.4.30, expat 1.95.4.
by the way, 'libxml2.dll' is not packed in the PHP 4.3 Windows distribution,
although it mentions that it does in the PHP documentation.
thanks in advance
