<code><?php
foreach ($menu as $key => $row) {
$menu_order[$key] = $row['menu_order'];
}
// 将数据根据menu_order升序排列
// 把 $menu 作为最后一个参数，以通用键排序
array_multisort($menu_order, SORT_ASC, $menu);</code>参照：http://php.net/manual/ja/function.array-multisort.php
使用自定义排序
<code>usort($menu, function($a, $b) {
return $a['menu_order'] < $b['menu_order'] ? -1 : 1;
});</code>
自定义排序 找到对应节点的值比较就行了吧
