Re: [PHP] Global Vars
$_GET['variable_name'] for GET variables and $_POST['variable_name'] for POST variables. Change the "variable_name" to whatever was in your form, for example the below variable name is "cust_name" For session it would be $_SESSION['session_name'] etc etc The above should get you going, but read up in the manual.

Re: [PHP] Global Vars
use $_POST['name_of_your_form_field'] or $_GET['name_of_your_form_field'] or $_REQUEST['name_of_your_form_field'] $_REQUEST contains $_GET, $_POST and $_COOKIE for server vars there is $_SERVER and $_ENV for environment vars $_SESSION is for session vars -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

Pretty hard to tell anything without any details about what you're doing...

Now the Website works perfect on my WAMP System with Apache 1.3.27 and PHP 4.3.0, but on my Linux Server the Login Functionality of the Website lets the User log in (Sessionmanagement is used at this point), but as i click on a link, the area where the username of the registered user should be shown, it shows just a number and doesnt let me log out. Instead it just shows a "0". Normaly it should be possible to do a login again from this point. On Windows everything works just fine. The Linux Machine is an Debain Woody / Apache 1.3.27 / php 4.2.3 Please help me, because my customers will jump on my neck if I dont, find out, where the problem is located. Hope you'll help me!

Re: [PHP] Global vars
global $var; does nothing outside of a function. You do not need to use global for this. $foo = 'bar'; include 'something_that_uses_foo.inc'; http://www.php.net/manual/en/language.variables.scope.php regards, Philip Olson On Sun, 2 Jun 2002, Anzak Wolf wrote: > I have a question about global vars.

Here's another way to have optional arguments, just so you're at a wealth
of solutions:
function function2()
{ list ($variable_A) = func_get_args();
}

Thanks for the pointer. I didn't realize that passing a blank argument
would achieve this effect.

function function2 ($variable_A="") {

It's in manual under "Functions" -- original isn't it? :)
