How to push a copy of an object into array in PHP

Question

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); ``` 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 ?

Accepted Answer

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;
```
