Dynamic Function Calling in PHP

Why php is more flexible ? See this function example:

Class Record

{

public function getMessage()

{

return "Hello world";

}
}

//You can call this function like this:

$function = "getMessage";

$R = new Record;

call_user_func( array($R, $function   )  );

If you want to pass some argument , you can use rest of the parameters of call-user_function;

eg: call_user_func( array($R, $function ) , $param, $param2);
