php copying array elements by value, not by reference

Question

I have the following code:

$data[\'x\'] = $this->x->getResults();  

$data[\'y\'] = $data[\'x\'];

//some code here to modify $data[\'y\']
//this cause         


        

Answer 1

array_flip() won't work when array values are not strings nor integers. I found a simple solution, however:

$clonedArr = (array)clone(object)$arr;

This works thanks to the properties of clone on an object.
