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

$array1= array(10,20,30,40,50);

        for($i = count($array1) - 1; $i >= 0; $i--)
        {
            $array2[]  = $array1[$i];

        }

        echo "<pre>";
            print_r($array2);
        echo "</pre>";

Answer 2

$item=end($array);
do {
...
} while ($item=prev($array));

Answer 3

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
}

Answer 4

This could be a more performant way since it doesnt construct a new array. It also handles empty arrays well.

$item = end($items);
while($item)
{
    ...do stuff...
    $item = prev($items);
}

Answer 5

$array = array_reverse($array);
foreach($array as $key => $currentElement) {}

This is better way to use. It will take care of keys also, if they are not sequential or integer.
