Moving Array Values

[Megahertza]

I'm trying to make a list of files in a directory and have them ordered by "last modified time". Can i move a array element to the end of a array.

example

array ([1] => one [2] => two [3] => three)
into
array ([1] => three [2] => two [3] => one)

Yes, by swapping them.

But seriously, you should look into sorting the array.

I don't know of a simple, one function call, way of doing that. However, in your example you're reversing the array, you could do that with a function:

$arr = array ('one','two','three');
$arr = array_reverse($arr);
// 0: three, 1: two, 2: one

To shift the first value to the last, make a function:

function myArrayShift($arr) {
  // Get the first item of the arry
  // and remove it
  $item = array_shift($arr);
  // Get the length of the array
  $len = count($arr);
  // Place $item on the end
  $arr[$len] = $item;
  // Return my altered array
  return $arr;
}

If one works with numeric indices, it is far simpler:

$max = count($array) - 1;
$temp = $array[0];
$array[0] = $array[$max];
$array[$max] = $temp;
