PHP實現數組遞迴排序

這次給大家帶來PHP實現數組遞迴排序，PHP實現數組遞迴排序的注意事項有哪些，下面就是實戰案例，一起來看一下。

本文執行個體講述了PHP數組遞迴排序實現方法。分享給大家供大家參考，具體如下：

/** * 遞迴根據特定key對數組排序 * @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));/** * 輸出：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) }}*/
