This would do it:
<?php
$first[] = 'hello';
$first[] = 'bye';
function swap(&$list, $first, $second)
{
$tempOne = $list[$first];
$list[$first] = $list[$second];
$list[$second] = $tempOne;
}
swap($first, 0, 1);
print_r($first);
?>

Subject: [PHP] Changing order of just one array item?
I need to change where one item is ordered in an array. I know how to sory an array, but I need to move one item up/down in the array. Example: $array is: 0 => "element one" 1 => "element two" 2 => "element three" 3 => "element four" I call array_order_up($array[1]) and $array is now: 0 => "element one" 2 => "element three" 1 => "element two" 3 => "element four"
If there aren't any native functions to do this, can anyone think of a way to make my own function to do this?
