You can call private methods with guetClosure():<?php
functioncall_private_method($object, $method, $args= array()) {
$reflection= new ReflectionClass(guet_class($object));$closure= $reflection->guetMethod($method)->guetClosure($object);
returncall_user_func_array($closure, $args);
}
classExample{
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.<?php
classA{
private $var= 'class A';
public function guetVar() {
return $this->var;
}
public function guetCl() {
return function () {
$this->guetVar();
};
}
}
class B{
private $var= 'class B';
}
$a= new A();
$b= new B();
print $a->guetVar() . PHP_EOL;
$reflection= new ReflectionClass(guet_class($a));
$closure= $reflection->guetMethod('guetVa ')->guetClosure($a);
$guet_var_b= $closure->bindTo($b, $b);
print$guet_var_b() . PHP_EOL;
// Output:
