This script fails with:

<b>Fatal error</b>:  Cannot redeclare test2() in <b>-</b> on line <b>4</b><br>

<?php

function test() {
	function test2() {
		echo "hi";
	}

	test2();
}

test();
test();
test();

?>

php has no "nested function" feature like you'll find in PASCAL 
or in gcc if you enable the feature

what happens here is that test2 is registered on execution of
test in the global namespace, and when you call test a second time
it cannot register test2 again

(the engine shouldn't  accept nested functions at all i think)
