Question

I want to move element of array present at 1st index to the 5th index in the array. How can I do that?

Answer 1

If you really mean “move”, than that can be something like this

$from = 1;
$to = 5;
$el = $array[$from];
unset($array[$from]);
$array = array_merge (
    array_slice($array,0,$to),
    array($el),
    array_slice($array,$to));

Cant test it, but the idea is: We take and remove the Element at $from from the original array, than we split the rest at $to and merge all together. Maybe some index in array_slice() does not match exactly;)
