Question

I am trying to use a global in a file that is just used to post data to. The global is not being registered on that page. How can I get the globals accessible in that page.

EDIT maybe I wasnt too clear so let me clear it up. I have these files

index.php

global $user;
echo $user->uid;

post.php

global $user;
echo $user->uid;

now from index.php I am posting to post.php through jquery. However when I echo $user->uid from post.php it is not echoing but when I echo it from index.php it is showing it. How can I get that $user->uid accessible from post.php.

Another way to access variables from the global scope is to use the special PHP-defined $GLOBALS array.

Example from php.net

<?php
$a = 1;
$b = 2;

function Sum() {
    $GLOBALS['b'] = $GLOBALS['a'] + $GLOBALS['b'];
} 

Sum();
echo $b;
?>
