PHP 5.2.12 - Interesting Switch Statement Bug With Integers and Strings
- by Levi Hackwith
<?php
$var = 0;
switch($var) {
case "a":
echo "I think var is a";
break;
case "b":
echo "I think var is b";
break;
case "c":
echo "I think var is c";
break;
default:
echo "I know var is $var";
break;
}
?>
Maybe someone else will find this fascinating and have an answer. If you run this, it outputs I think the var is a when clearly it's 0. Now, I'm most certain this has something to do with the fact that we're using strings in our switch statement but the variable we're checking is an integer. Does anyone know why PHP behaves this way? It's nothing too major, but it did give me a bit of a headache today.
Thanks folks!
