Hi,

it would be very useful if `class_implements()`/class_parents() would also 
handle a string containing a class name instead of requiring an object 
instance.

regards,
Lukas

Class as it says does not need an instance. Can you send a patch?

  Hello Marcus, Lucas,
I have made a patch for `class_implements()` :

The function is here :

and this is the test script :
./php -r 'interface iface1{}interface iface2{} class a implements iface1, iface2{} 
var_dump(class_implements(new a), class_implements("a"), class_implements("aaa"), 
class_implements("bbb", 0)); function __autoload($cname){ var_dump($cname);}'

or

<?php
interface iface1{}
interface iface2{}
class a implements iface1, iface2{}
var_dump(class_implements(new a),
          class_implements("a"),
          class_implements("aaa"),
          class_implements("bbb", 0)
);

function __autoload($cname){
     var_dump($cname);
}
?
