In PHP, how do I deep copy arrays with SPL?

In PHP, you can deep copy arrays using the Standard PHP Library (SPL). The SPL provides a rich set of built-in classes to work with data structures, including arrays. To achieve a deep copy, you can utilize the `ArrayObject` class along with some built-in methods.

Here’s an example of how to deep copy an array using SPL:

<?php // Original array with nested structure $originalArray = [ 'name' => 'John', 'details' => [ 'age' => 30, 'address' => [ 'city' => 'New York', 'state' => 'NY' ] ] ]; // Creating a deep copy using ArrayObject $arrayObject = new ArrayObject($originalArray); $deepCopyArray = $arrayObject->getArrayCopy(); // Modifying the deep copy $deepCopyArray['details']['age'] = 31; // Original array remains unchanged print_r($originalArray); print_r($deepCopyArray); ?>
