Question

This should be really simple, but what is the way to go on this. I want to sort an multidimensional array by a key, like this:

Array (
[0] => Array
    (         


        

Answer 1

I have added this answer at Sort multi-dimensional array by specific key sort the array specific key to sorting array value.

function sortBy($field, &$array, $direction = 'asc')
{
    usort($array, create_function('$a, $b', '
        $a = $a["' . $field . '"];
        $b = $b["' . $field . '"];

        if ($a == $b)
        {
            return 0;
        }

        return ($a ' . ($direction == 'desc' ? '>' : '<') .' $b) ? -1 : 1;
    '));

    return true;
}

Call this function by specific array key

sortBy('status',   $array);
