How can the use of Array Iterator in PHP help optimize code performance?

Using Array Iterator in PHP can help optimize code performance by providing a more efficient way to iterate over arrays compared to traditional loops like foreach. Array Iterator allows for more control over the iteration process and can potentially reduce memory usage and improve execution speed. 

// Using Array Iterator to optimize code performance
$array = [1, 2, 3, 4, 5];
$iterator = new ArrayIterator($array);

while($iterator->valid()) {
    echo $iterator->current() . "\n";
    $iterator->next();
}
