Hi Shawn, I've updated your function to do the $before bit:



I also set it up to merge the new array to the end if the key does not exist.

Out of all the examples I have found, your approach looks the cleanest
and the most compact.

I'm open to feedback.

Many thanks

Cheers,
M

Might be an easier way but this should work.  You can sort the $before =
true out for yourself :-)

function array_insert(&$array, $key, $insert, $before = FALSE) {
$i = 0;
foreach($array as $k => $v) {
  if($k === $key) {
$p = $i + 1;
break;
  }
  $i++;
}
$array = array_merge(array_slice($array, 0, $p), $insert,
array_slice($array, $p, count($array) - $p));
}
