Remove object reference from array of objects in PHP

Im trying to copy array of objects to a new array. but the reference to the objects in the array are staying the same. my code :

$newArray = $this->ContentArray;
var_dump(newArray[0]->text); //print "text"
var_dump($this->ContentArray[0]->text); //print "text"
$this->ContentArray[0]->text = "edit text"; 
var_dump(newArray[0]->text); //print edit text"

how can I remove the reference to the objects?

You could explicitely clone each array element:

$newArray = array_map(
    function ($element) { return clone $element; },
    $this->ContentArray
);
array_merge($this->ContentArray,$newArray);

var_dump(newArray[0]->text);
var_dump($this->ContentArray[0]->text);
$this->ContentArray[0]->text = "edit text"; 
var_dump(newArray[0]->text);

But I prefer the solution from Praveen Kumar.

You got a typo: $this-ContentArray[0]->text = "edit text";

Should be $this->ContentArray[0]->text = "edit text";

EDIT And you have tried putting '$' before newArray?

EDIT 2

It seems that Objects in PHP are always passed by reference, even if you. You might want to check out this thread: Passed by reference
