[PHP] Execing problems
Hi all, I have a seperate perl script that I need to start running from a php script. The script does a fork into the backgroup and exits. when i do an exec(funky script stuff here); The page just hangs trying to load again, apparently after I call the exec. I've also tried exec(script stuff ) but it does the same thing. Any ideas anybody ?

RE: [PHP] Execing problems
does using system() work? what about back-ticks? - `funky script stuff here`; I'll give it a go, i hadn't tried that Although I thought system would return the output. I was using exec because it didn't (oops I think I forgot to mention that.) Jason -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
[PHP] Syntax high lighting
Hi all, A few months ago I saw a php class (?) for doing syntax high lighting of various programming languages. But I lost the link in a compter crash and now I cant find it again. does anybody know of a php script to do this sort of code highlighting similar to the show_source() function for php, but for c++,c,perl etc etc ?

[PHP] Global Arrays ?
Hi all, I've got an array in the global scope called $g_months which oddly enough contains the names of the months. Now when I try to import this into a function as global $g_months; it doesn't work. When php prints out the array as an option box I just wind up with no options. Any ideas why this is the case ? Am I doing something wrong ?

Re: [PHP] Global Arrays ?
Sounds quite odd - you may try an echo(serialize($g_months)) in the
function and see what you get... It may be that the code generating the
option box has problems - this way you make sure $g_months is empty indeed.
Thanks for that. IT appears to be a problem with the function itself, as
the array is full of stuff.
I guess the next question is, what am i doing wrong here, that lets it
work with a local array but not a global one ?
function html_option_months($selected_month) {
global $g_months;
echo(serialize($g_months));
$result = ;
while (list($key, $val) = each($g_months)) {
$result .= html_option($key,$val, ($selected_month == $key));
}
return $result;
}

Re: [PHP] Global Arrays ?
It may be a bug in your PHP - walking an array with each probably sets some internal position marker which may be buggy for your very situation (global variable in local function - something like that). Thanks for that. I tried it with foreach and it works now.

[PHP] Bookmarking pages
Hi all, again, I need to be able to have working bookmarkable pages in a system. The user has session ID's which have to time out, so when they do the user is kicked out of the system. But i've been asked to set it up so that after a user gets kicked to a login screen becasue they have an expired/invalid session id, to let them go back to the page they where on before getting booted. No all of the non-session id variables will be in the $HTTP_GET_VARS array (right ?), but how do I get the file that the user has just come from ?

[PHP] Quoting strings
Hi all, I have a fnction that needs to quote a strings in php to make them easy to stick into an mysql db. I need to do basically $msg, which is easy enough, but I would like to not quote strings that are already quoted and also escape any single or double quotes in the string. IS there a regex to do this that anybody knows of, or a php function that i;ve missed ? Ideas anybody ?

[PHP] php 4.0.6 and imap support
Hi all, I tried to find an answer to this but nothing seemed to work. I need to build php 4.0.6 with imap support. I'm running redhat 7.1 and have build and installed the imap-2000-9 rpm's (including devel), php will build correctly but complains about an undefined symbol mxdriver. Has the library changed ? Is the lib it is looking for in the wrong spot ? Have a linked it wrong ??

[PHP] Modssl php 4 fears
Hi again all, I recompiled apache with modssl and it works. (Well the snake oil inc cert's work ;) But i get a warning on apache load about, loading a standard module (php4.so) and how this may crash becasue it isn't compiled to work with EAPI. Please comile with -DEAPI Now the question is, do i need to worry about this ? I just did a quick recompile of PHP but didn't change the config at all. Hence no -DEAPI.

[PHP] HTTP Authentication and PHP
Hi all,
I've been playing around with PHP authentication via HTTP.
I'm using apache, and when i use the header('WWW_Auth...)
headers i get a username/password dialog pop up (as i wanted).
How do i get those values unset in the browser, so that i can get a user
to re authenticate ?
I need to get a user to re-auth part way through the use of the app i'm
writing becasue they are deleting files from a file system.
Also how would i allow them to logout and let someone else log in.
The docs seemed to imply that the headers command should have repopped the
auth box.

[PHP] File Upload Headaches
Hi all, Can anybody see what is wrong with this code ?? echo \$userfile = $userfile; echo $HTTP_POST_FILES['userfile']['tmp_name']; // now to provide an assignment submission box print P; print FORM ENC_TYPE=\multipart/form-data\ ACTION=\$paramupload=true\ METHOD=\post\ \n; print INPUT TYPE=\hidden\ NAME=\MAX_FILE_SIZE\ VALUE=\1048576\\n; print H4Submit A File/H4P ; print INPUT TYPE=\file\ NAME=\userfile\ \nP; print INPUT TYPE=\submit\ VALUE=\Upload\\n; print /FORM; this is just a code fragment but, essentially the form submits back to itself. When i try to output the $HTTP_POST_FILE['userfile']['any thing'] variables they are not set, and $userfile is simply set to the filename on the other computer.

Re: [PHP] Output (Urgent!)

if ($resolution = '1024') {
$resolution = 1024;
} else {

It always output 1024
At a guess becasue your mixing and matching languages.
If you got the input from a hidden field in a form (perhaps an entry
page?) then it would be possible to get the data you want.

RE: [PHP] learning PHP from scratch
This approach worked pretty well with previous people i teached PHP, but they already had some sort of programming background. This guy hasn't. I find that he has some difficulties picking it up. And I have some difficulties to further help him. Is he having problems with PHP, or database interaction with PHP? It sounds like he might be having problems with the basic programming concepts. Are you teaching him and then getting the guy to actaully try some for himself ? Start with something really basic, (hello world) and get him to do a couple of dynamic things that dont use the database, then introduce the db slowly. Give him some hands on programming task to get started with, and rpovide him with a good book on PHP and encourage him to experiment a bit.

[PHP] Session questions
Hi all,
This might be a dumb question but can anybody tell me why on earth this
doesn't work ?
session_start()
$logged_in = session_is_registered(auth);
if($logged_in != true)
{
if(!(pam_auth($usernamelogin,$pass,$error)))
{
// send an error if it doens't login in
}
else
{
session_register($username);
session_register($auth);
$HTTP_SESSION_VARS[username] = $usernamelogin;
$HTTP_SESSION_VARS[auth] = 1;
}
$user = $HTTP_SESSION_VARS[username];
start_page($user's home page);
}
Now the problem is, that although it auth's ok, and username and auth seem
to be set, anytime i try to access $HTTP_SESSION_VARS[username] it is
blank.
Also if i try to use $HTTP_SESSION_VARS[username] directly in a string i
get and error about expecting one of a variety of string types.
Sorry if this is a really dumb question.

[PHP] User Authentication
Hi all, Is there a way in php4 to authenticate a user against the system passwords? I have to write a php program to handle student assignment submissions. These users need to authenticated against an winnt PDC. Samba has a package called winbind that will let me map the pdc's usernames and groups onto the unix ones, with the help of pam. Now i then need to access those throught (i assume) the unix getpwent and getgrent commands, so that winbind will be used as the service to lookup the names and passwords. Is this functionality available in php ? If not, anybody got any pointers on how to go about writing a wrapper for php for this ??
