Note, that in php's comparison table it says "php"==0 is true, so if:
(second table: http://www.php.net/manual/en/types.comparisons.php)

<?php

$foo = in_array(0, array("x", "y")); // foo is TRUE!!!!! AAAH!

?>

because 0 and any string is equal. Of course, 0==="php" is not equal, false, but 0==="0" false too.

nice comparison tables by the way...
