PHP: Move associative array element to beginning of array

Question

What would be the best method of moving any element of an associative array to the beginning of the array?

For example, say I have the following array:

Answer 1

There's a function in the comments of the PHP manual for array_unshift which can be used to add an element, with key, to the beginning of an array:

function array_unshift_assoc(&$arr, $key, $val)
{
    $arr = array_reverse($arr, true);
    $arr[$key] = $val;
    return array_reverse($arr, true);
}

Unset the element and reinsert it again with the above function:

$tmp = $myArray['one'];
unset($myArray['one']);
$myArray = array_unshift_assoc($myArray, 'one', $tmp);

A more general approach may be to use uksort to sort your array by keys and provide a sorting function of your own.
