PHP comparison is so inconsistent.
Raw
inconsistent_comparison.php
<?php
var_dump(null == 0); // evaluates to true
var_dump(null < -1); // this also evaluates to true
// so, how can some predefined value be equal to 0 as well as be less than -1?
?>

null evaluates to "0" when you compare to numeric values.
