You can call private methods with getClosure():<?phpfunction call_private_method($object, $method, $args = array()) { $reflection = new ReflectionClass(get_class($object)); $closure = $reflection->getMethod($method)->getClosure($object); return call_user_func_array($closure, $args);}class Example { private $x = 1, $y = 10; private function sum() { print $this->x + $this->y; }}call_private_method(new Example(), 'sum');?>Output is 11.Use method from another class context.<?phpclass A { private $var = 'class A'; public function getVar() { return $this->var; } public function getCl() { return function () { $this->getVar(); }; }}class B { private $var = 'class B';}$a = new A();$b = new B();print $a->getVar() . PHP_EOL;$reflection = new ReflectionClass(get_class($a));$closure = $reflection->getMethod('getVar')->getClosure($a);$get_var_b = $closure->bindTo($b, $b);print $get_var_b() . PHP_EOL;// Output:// class A// class B
