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

$array=array(
    0 => 0,
    '1' => 1,
    2 => null,
    3 => false
);

$value=end( $array );                      // ← value for first iteration
while(($key=key( $array )) !== null) {
  echo "key=$key, value=$value\n";

  $value=prev( $array );                   // ← value for next iteration
}
