In PHP, how do I deep copy arrays in vanilla PHP?

In vanilla PHP, you can perform a deep copy of an array by utilizing the serialization method. The process involves serializing the original array and then deserializing it to create a completely independent copy. This ensures that nested arrays are also copied by value rather than by reference.

<?php function deepCopy($array) { return unserialize(serialize($array)); } $originalArray = [ 'a' => 1, 'b' => ['c' => 2, 'd' => 3], ]; $copiedArray = deepCopy($originalArray); // Modify the copied array $copiedArray['b']['c'] = 4; // Outputs: 1 echo $originalArray['b']['c']; ?>
