cool thingy

[legohead6]

Hi, Like always i was fiddling around with code(this time arrays) and i stumbled apon something cool! put this in a php pahe and upload it to your webserver! its kinda handy

[code]foreach($_SERVER as $id => $value){
echo "$id: $value<br>";
}[/code]

Everyone uses those all the time in their scripts! These variables are called [a href=\"http://uk2.php.net/variables.predefined\" target=\"_blank\"]Super Globals[/a]. There are also other prefined variables too in PHP.

... Which are documented here:

[a href=\"http://www.php.net/variables.predefined\" target=\"_blank\"]http://www.php.net/variables.predefined[/a]

And a much easier way of dumping any of them or any array (or variable) is
[code]<?php echo '<pre>' . print_r($thearray,true) . '</pre>'; ?>[/code]
