Yes, I know, but not everyone has Reflection API, reflection slow...

I think reflection extension allows to do such checks.

So, maybe new function for checking interface implementation for
classes?? Like bool is_implementing(mixed $class_or_object, string
$interface)
[2007-04-19 15:01:33] [EMAIL PROTECTED]
quoting the manual (http://php.net/is_a):
bool is_a ( object $object, string $class_name )
Checks if the given object is of this class or has this class as one
of its parents.
'foo' is not an object (it is a string), and therefore is_a()
returns false.
is_a('foo', 'foo')
is also false for the same reason.

Description:
is_a function will be works if first argument is class name and next
argument is interface name. Currently it isn't working... I can't check
for class (not object) is implementing some interface
Reproduce code:
---
?php
inteface factory
{
public static function _factory($params);
}
class foo implements factory
{
public static function _factory($params)
{
$t = new foo();
return $t; // Sweet use of factory ;)
}
}
var_dump
(
is_a('foo', 'factory'), // Currently return false, but true is
expected
is_a($foo = new foo(), 'factory') // It is working but it isn't
practicly
);
?
Expected result:
bool(true)
bool(true)
Actual result:
--
bool(false)
bool(true)
