php implementation to keep us happy for now

--was--
Sorry, two corrections to that function. My variables were not clear and I wasn't checking if
the class passed in was the same type as match (I was going straight to the parent)
if (!function_exists('is_a')) {
function is_a($class, $match)
{
if (empty($class)) {
return false;
}
$class = is_object($class) ? get_class($class) : $class;
if (strtolower($class) == strtolower($match)) {
return true;
}
return is_a(get_parent_class($class), $match);
}
}
