Object.hasOwnProperty.call(object, key) in php

Question

Is there an equivalent of this JavaScript code in PHP?

var object = {}, key;
Object.hasOwnProperty.call(object, key) 

Answer 1

Or using reflection (See: http://www.php.net/manual/en/book.reflection.php):

<?php
$obj = (object)array('test' => 1);
$key = 'test';

$refObj = new ReflectionObject($obj);
var_dump($refObj->hasProperty($key));

Answer 2

for properties:

property_exists($class_instance, 'YourProperty');

for methods:

method_exists($class_instance, 'YourMethod');
