Description:
------------
When comparing number zero with a not empty string, it returns true.

if($something) {
    echo $something . "is true. <br />";
}
if ("thestring") {
    echo "thestring is true" . "<br />";
}
if ($something == "thestring") {
    echo "why?" . "<br />";
}
if("thestring" == $something) {
    echo "again why?" . "<br />";
}   
?>
