i want to be able to change the last key from array i try with this function i made:
function getlastimage($newkey){
$arr = $_SESSION['files'];
$oldkey = array_pop(array_keys($arr));
$arr[$newkey] = $arr[$oldkey];
unset($arr[$oldkey]);
$results = end($arr);
//echo json_encode($results);
print_r($arr);
}
if i call the function getlastimage('newkey') it change the key!but after if i print the $_SESSION the key is not changed? why this?
