In PHP, how do I iterate over arrays with SPL?

Iterating over arrays in PHP using SPL can be accomplished with various SPL classes like SPLFixedArray or ArrayIterator. Below is an example using ArrayIterator:


        <?php
        // Create an array
        $array = array('one', 'two', 'three', 'four', 'five');

        // Create an ArrayIterator
        $iterator = new ArrayIterator($array);

        // Iterate using foreach
        foreach ($iterator as $key => $value) {
            echo "Key: $key, Value: $value<br>";
        }
        ?>
