Hi Jim,
The code you posted is correct, I never contested that. Read carefully.
<?php
function not_super()
{
var_dump(isset($GLOBALS['GLOBALS']));
$a = array_keys($GLOBALS);
var_dump(isset($a['GLOBALS']));
}
not_super();
?>
run this code, don't read it, you will see output of bool(false), bool(false)
However, the following code works as expected!
<?php
function not_super()
{
return array_keys($GLOBALS);
}
var_dump(not_super(), array_keys($GLOBALS));
?>
GLOBALS will be present in both arrays.
Very odd behavior.
Greg

actually, it does work and it does exist. Try using print_r() or print_r(array_keys($GLOBALS)); and you will see an entry for GLOBALS mine is located at #13 Jim Lucas ----- Original Message ----- From: "Greg Beaver" <greg@chiaraquartet.net> To: "Leif K-Brooks" <eurleif@buyer-brokerage.com> Cc: <php-general@lists.php.net> Sent: Friday, August 01, 2003 12:45 PM Subject: Re: [PHP] Re: GlobalsTry this code: <?php function blah() { var_dump($GLOBALS['GLOBALS']); } blah(); ?> It appears that in a function scope, it doesn't. This is definitely a bug, I'll post it if it hasn't already been noticed.
