Iterate in reverse through an array with PHP - SPL solution?

Question

Is there an SPL Reverse array iterator in PHP? And if not, what would be the best way to achieve it?

I could simply do

$array = array_reverse($array)         


        

Answer 1

Note that if you want to preserve the keys of the array, you must pass true as the second parameter to array_reverse:

$array = array_reverse($array, true);
foreach ($array as $currentElement) {
    // do something here
}
