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

References to the same objects already get copied when you copy the array. But it sounds like you want to shallow-copy deep-copy the objects being referenced in the first array when you create the second array, so you get two arrays of distinct but similar objects.

The most intuitive way I can come up with right now is a loop; there may be simpler or more elegant solutions out there:

$new = array();

foreach ($old as $k => $v) {
    $new[$k] = clone $v;
}
