method invoke

[vurentjie]

hi,

 

i am fiddling with the php reflection classes today,

 

i was wondering what the first argument to method->invoke would do...

 

class Greet{    
   
    final public static function saystuff($hi,$bye){

        return $hi." and ".$bye;

    }

}

$method = new ReflectionMethod('Greet','saystuff');
echo $method->invoke(NULL,"hallo","tchuss");
echo $method->invoke('anythinggoes',"hallo","tchuss");

 

?

 

...EDIT...nevermind I just figured it out - it has to do with calling static method or non-static method,

 

 

class Greet{    
   
    public function saystuff($hi,$bye){

        return $hi." and ".$bye;

    }

}

$greeting = new Gree();
$method = new ReflectionMethod('Greet','saystuff');

echo $method->invoke(NULL,"hallo","tchuss"); //exception
echo $method->invoke($greeting,"hallo","tchuss"); //will work

per the  site: http://nz.php.net/oop5.reflection (about halfway down)

 

For static methods, you should pass NULL as the first argument to invoke(). For non-static methods, pass an instance of the class.

 

So, your example would probably trigger an exception.
