Regarding my previous post:

For checking whether a value is not an array, it seems to be better to use !== in some cases. I'm checking an array member, and it works when using !== but not ! ... ===.

So use:
<?php
if ((array) $test[0] !== $test[0])
	echo 'it\'s not an array';
?>

Instead of:
<?php
if (!(array) $test[0] === $test[0])
	echo 'it\'s not an array';
?>
