php 數組排序

對下面數組中欄位menu_order排序，怎麼解？？？？？？

Array
(

[menu] => Array    (        [0] => Array            (                [menu_name] => 首頁                [login_menu_name] =>                 [icon] => glyphicon glyphicon-home                [menu_href] => /api/1ek2n5gsut/shop/                [login_menu_href] => /api/1ek2n5gsut/shop/                [bind_action_attr] => 0                [menu_order] => 4            )        [1] => Array            (                [menu_name] => 我要分銷                [login_menu_name] => 分銷中心                [icon] => glyphicon glyphicon-indent-left                [menu_href] => /api/1ek2n5gsut/distribute/join/                [login_menu_href] => /api/1ek2n5gsut/distribute/                [bind_action_attr] => 1                [menu_order] => 3            )        [2] => Array            (                [menu_name] => 購物車                [login_menu_name] =>                 [icon] => glyphicon glyphicon-shopping-cart                [menu_href] => /api/1ek2n5gsut/shop/cart/                [login_menu_href] => /api/1ek2n5gsut/shop/cart/                [bind_action_attr] => 2                [menu_order] => 1            )        [3] => Array            (                [menu_name] => 個人中心                [login_menu_name] =>                 [icon] => glyphicon glyphicon-user                [menu_href] => /api/1ek2n5gsut/shop/member/                [login_menu_href] => /api/1ek2n5gsut/shop/member/                [bind_action_attr] => 0                [menu_order] => 1            )        [4] => Array            (                [menu_name] => 分類                [login_menu_name] =>                 [icon] => glyphicon glyphicon-th-list                [menu_href] => /api/1ek2n5gsut/shop/3//allcategory/                [login_menu_href] => /api/1ek2n5gsut/shop/3//allcategory/                [bind_action_attr] => 0                [menu_order] =>             )    )[method] =>

)

 $row) {    $menu_order[$key] = $row['menu_order'];}// 將資料根據menu_order升序排列// 把 $menu 作為最後一個參數，以通用鍵排序array_multisort($menu_order, SORT_ASC, $menu);

參照：http://php.net/manual/ja/function.array-multisort.php

使用自訂排序

usort($menu, function($a, $b) {    return $a['menu_order'] < $b['menu_order'] ? -1 : 1;});

自訂排序 找到對應節點的值比較就行了吧
