You can call private methods with getClosure():
<?php
function 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.
