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.

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

Try 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.

Yes it does. I just ran the following, and I got "Greg is wrong."

<?php
$foo = 'Greg is wrong.';
echo $GLOBALS['GLOBALS']['GLOBALS']['GLOBALS']['foo'];
?>
