uncamelize - Inflector Helper Extension

[eluser]darkhouse[/eluser]
I needed to take some camelized strings and convert them back to regular strings, so I made this little function to extend the inflector helper. I know it's not much, but I searched the forums for it and couldn't find anything, so here it is if anyone needs it.

Code:

if(!function_exists('uncamelize')){
    function uncamelize($str, $delimiter=' '){
        $str = strtolower(preg_replace('/([A-Z])/', $delimiter.'$1', $str));
        return $str;
    }
}
