consider the following code snippet:
<?
function foo() {
global $bar;
$bar="hello";
}
foo();
echo $bar;
?>
in PHP 3 calling foo() will create a global variable $bar
if it doesn't exist
in PHP 4 there will be no $bar after calling foo
i think PHP 4 should behave like PHP 3 here not only due
to compatibility reasons but also due to the "least supprise" rule
