How to clone an array of objects in PHP?

Question

I have an array of objects. I know that objects get assigned by \"reference\" and arrays by \"value\". But when I assign the array, each element of the array is referencing

Answer 1

You need to clone objects to avoid having references to the same object.

function array_copy($arr) {
    $newArray = array();
    foreach($arr as $key => $value) {
        if(is_array($value)) $newArray[$key] = array_copy($value);
        else if(is_object($value)) $newArray[$key] = clone $value;
        else $newArray[$key] = $value;
    }
    return $newArray;
}
