umm... That is what is going to happen when you follow your example.
I think you are mistaken in what you are expecting...
This line:
$a = array_keys($GLOBALS);
will give you an array of values that match the keys of the $GLOBALS array
it won't copy the arrays.
Try this.
<PRE>
<?php
$a = array_keys($GLOBALS);
foreach($a AS $key => $value) {
echo $key."=>(".$value.")\n";
}
?>
