It makes no sense to write a function exactly like the one you posted, because the function will always return TRUE. However it can be useful to have multiple return points based on different conditions.

PHP Code:


			
// Useless example
function do_something($with_arg = NULL)
{
    if ($with_arg === NULL)
        return FALSE;

    echo 'Arg is: ';
    var_dump($arg);
    return TRUE;
}
