如何把一个对象的副本到PHP数组

问题描述

我试图对象添加到PHP数组，但它没有工作，尝试2种方法：

I tried to add objects into array in PHP but it didn't work, tried 2 methods:

1

$obj->var1 = 'string1';
$obj->var2 = 'string1';
$arr[] = $obj;
$obj->var1 = 'string2';
$obj->var2 = 'string2';
$arr[] = $obj;

2

$obj->var1 = 'string1';
$obj->var2 = 'string1';
array_push($arr,$obj);
$obj->var1 = 'string2';
$obj->var2 = 'string2';
array_push($arr,$obj);

这两种方法都将增加最新的对象到整个磁盘阵列。似乎对象被添加到由参考阵列。有没有办法通过值他们加入到数组？

Both methods will add the latest object into entire array. Seems that object is added to the array by reference. Is there a way to add they into array by value ?

推荐答案

对象总是通过引用在PHP 5或更高版本通过。如果你想要一个副本，您可以使用克隆算

Objects are always passed by reference in php 5 or later. If you want a copy, you can use the clone operator

$obj = new MyClass;
$arr[] = clone $obj;
