Here is an array:

$array = (0 => "pear", 1 => "apple", 2 => "orange", 3 => "kiwi");

What is the best way to reorder the array to become:

$array = (0 => "pear", 1 => "kiwi", 2 => "orange", 3 => "apple");

Edit:

Please note I am not looking for an alphabetical sort. I am looking to switch the order of two items within an array. My initial thought was to pop out the key=>value pair that I want to change, then reinsert it. But I want to know if there is a better way.

Answer 1

Use this code to switch 2 values of your array:

$tmp = $array[1];
$array[1] = $array[3];
$array[3] = $tmp;
unset($tmp); // you may delete the variable if you no longer need it
