Sort PHP multi-dimensional array based on value in inner array?

array_multisort() - Sort multiple or multi-dimensional arrays

Thinking,more useful and practical http://php.net/manual/en/function.sort.php

function array_sort($array, $on, $order=SORT_ASC){

    $new_array = array();
    $sortable_array = array();

    if (count($array) > 0) {
        foreach ($array as $k => $v) {
            if (is_array($v)) {
                foreach ($v as $k2 => $v2) {
                    if ($k2 == $on) {
                        $sortable_array[$k] = $v2;
                    }
                }
            } else {
                $sortable_array[$k] = $v;
            }
        }

        switch ($order) {
            case SORT_ASC:
                asort($sortable_array);
                break;
            case SORT_DESC:
                arsort($sortable_array);
                break;
        }

        foreach ($sortable_array as $k => $v) {
            $new_array[$k] = $array[$k];
        }
    }

    return $new_array;
}

How to use

 $list = array(
   array( 'type' => 'suite', 'name'=>'A-Name'),
   array( 'type' => 'suite', 'name'=>'C-Name'),
   array( 'type' => 'suite', 'name'=>'B-Name')
 );

$list = array_sort($list, 'name', SORT_ASC);

array(3) { [0]=> array(2) { ["type"]=> string(5) "suite" ["name"]=> string(6) "A-Name"    } [2]=> array(2) { ["type"]=> string(5) "suite" ["name"]=> string(6) "B-Name" } [1]=> array(2) { ["type"]=> string(5) "suite" ["name"]=> string(6) "C-Name" } }

Try this usort function:

    function cmp($a, $b){
        if ($a == $b)
            return 0;
        return ($a['name'] < $b['name']) ? -1 : 1;
    }

$my_array = array(
0 => array
    (
        'type' => 'suite'
        ,'name' => 'A-Name'
    )
,1 => array
    (
        'type' => 'suite'
        ,'name' => 'C-Name'
    )
,2 => array
    (
        'type' => 'suite'
        ,'name' => 'B-Name'
    )
);


usort($my_array, "cmp");

If you using it in a class, the second parameter changes to an array like this:

usort($my_array, array($this,'cmp'));
