Just curious about something I came across.
I was looking at the $GLOBAL array, to see what my script was leaving behind.
$GLOBALS contains a reference to itself.
Even though its a reference, whats the sense with that??
Once its global, why should it have to call on itself?
Im currently running php 4.3.4 on FreeBSD 4.9
Thanks
A script to try out ->
<?php
header('content-type: text/plain');
var_dump(isset($GLOBALS['GLOBALS']['GLOBALS'])); // returns true
// Prints out the $GLOBALS array
// including one reference to itself
// then starts another but quits with *RECURSION*
var_dump($GLOBALS);
?>
