An example of how to concatenate arrays in PHP using the Standard PHP Library (SPL).


        <?php
        $array1 = new ArrayObject([1, 2, 3]);
        $array2 = new ArrayObject([4, 5, 6]);

        // Concatenate the arrays using ArrayObject
        $array1->exchangeArray(array_merge($array1->getArrayCopy(), $array2->getArrayCopy()));

        $result = $array1->getArrayCopy();
        print_r($result);
        ?>
