In PHP, how do I merge objects with SPL?

In PHP, you can use the Standard PHP Library (SPL) to merge objects. You can achieve this by using the ArrayObject class which allows objects to be treated like arrays. Here’s how you can do it:


    <?php
    class ObjectA {
        public $a = 'Hello';
        public $b = 'World';
    }

    class ObjectB {
        public $c = 'This';
        public $d = 'is PHP';
    }

    $obj1 = new ObjectA();
    $obj2 = new ObjectB();

    // Convert objects to arrays
    $array1 = (array)$obj1;
    $array2 = (array)$obj2;

    // Merge arrays
    $mergedArray = array_merge($array1, $array2);

    // Convert merged array back to an object
    $mergedObject = (object)$mergedArray;

    print_r($mergedObject);
    ?>
