session

<?php
session_start();
$auth="true";
session_register('auth');
call()
?>
<Br><BR>
test

<?php
function call()
{
echo $auth;
}
?>

this script returns:

Warning: Undefined variable: auth in test.php on line 13

test

Why can't i use a session variable in a function?

It's ok i get it.
The problem could be solved like this:

<?php
session_start();
$auth="true";
session_register('auth');
call($auth)
?>
<Br><BR>
test

<?php
function call($a)
{
echo $a;
}
?>

you need a global statement.

$var="anything"
function blah() {
global $var;
print $var;
}

If you wanna use your session var inside a function, you have to declare it as a global variable first (1st line of your function)...

function call()
{global $auth;
echo $auth;
}
