本文实例讲述了PHP数组递归排序实现方法。分享给大家供大家参考，具体如下：

/** * 递归根据特定key对数组排序 * @param $data * @param string $orderKey * @param string $sonKey * @param int $orderBy * @return mixed */function recursion_orderby($data, $orderKey = "order", $sonKey = "children", $orderBy = SORT_ASC){  $func = function ($value) use ($sonKey, $orderKey, $orderBy) {    if (isset($value[$sonKey]) && is_array($value[$sonKey])) {      $value[$sonKey] = recursion_orderby($value[$sonKey], $orderKey, $sonKey, $orderBy);    }    return $value;  };  return array_orderby(array_map($func, $data), $orderKey, $orderBy);}$a = [  [    "order" => 0,  ],  [    "order" => -1,    "children" => [      [        "order" => 0,      ],      [        "order" => -2,        "children" => [          ["order" => 0],          ["order" => -1],          ["order" => 1],        ],      ],    ],  ],  [    "order" => 2,  ],];var_dump(recursion_orderby($a));/** * 输出：array(3) { [0] => array(2) {  "order" =>  int(-1)  "children" =>  array(2) {   [0] =>   array(2) {    "order" =>    int(-2)    "children" =>    array(3) {     [0] =>     array(1) {      "order" =>      int(-1)     }     [1] =>     array(1) {      "order" =>      int(0)     }     [2] =>     array(1) {      "order" =>      int(1)     }    }   }   [1] =>   array(1) {    "order" =>    int(0)   }  } } [1] => array(1) {  "order" =>  int(0) } [2] => array(1) {  "order" =>  int(2) }}*/

注：这里的array_orderby方法在前面一篇《php自定义二维数组排序函数array_orderby用法》中有详细介绍

PS：这里再为大家推荐一款关于排序的演示工具供大家参考：
