Question

Following code:

<?php
$str = "19.09.02";
if(substr($str, -3, 2) == ".0")
{
    // Doing something
}

$str2 = "19.09.2002";
if(substr($str2, -3, 2) == ".0")
{
    // Doing something
}
?>

Why does the second statement apply (without regexp)? and how can I solve, that it just apply the first expression?

Thank you

I think you should use the identity (===) operator to fix this 🙂

One of the main differences of === vs == is that === doesn’t cast at all, it is a very strict comparison.
