PHP实现指定字段的多维数组排序函数分享,多维数组

PHP数组排序可以用array_multisort方法实现,但是如果是多维数组,并且我们要指定数组中的某个字段进行排序,那么这就需要我们自己写方法实现了。本文分享了一段PHP指定字段的多维数组排序方法的代码,这段代码可实现根据field字段对数组进行排序。
复制代码 代码如下:
function sortArrByField(&$array, $field, $desc = false){
  $fieldArr = array();
  foreach ($array as $k => $v) {
    $fieldArr[$k] = $v[$field];
  }
  $sort = $desc == false ? SORT_ASC : SORT_DESC;
  array_multisort($fieldArr, $sort, $array);
}

以上就是PHP指定字段的多维数组排序方法,希望这段PHP代码对你带来帮助。
