在数组对象按引用传递？ [英] Are objects in array passed by reference?

问题描述

在像下面的情况，

class my_class {

    public __construct($params = array()){

        **** do something
    } 

 }

 $other_object = new some_class();

 $object = new my_class(array(
                         'var1' => 'test' 
                         'object' => $other_object));

$ other_object 将被引用或按值传递？

$other_object will be passed by reference or by value?

推荐答案

对象总是引用，除非你克隆它明确。

Objects are always references, except you clone it explicitly.

您可以使用 spl_object_hash（） 检索对象ID，然后比较它们彼此。请记住，一旦一个物体被从存储器由垃圾收集移除，ID可以被重用。

You can use spl_object_hash() to retrieve the "object id" and then compare them against each other. Remember, that once an object is removed from the memory by the garbage collector, the ID may get reused.
