PHP多维数组排序array详解

php数组array按字段排序

  /**
   * sort array by filed and type, common utility method.
   * @param array $data
   * @param string $sort_filed
   * @param string $sort_type sort_asc or sort_desc
   */
  public function sortbyonefield($data, $filed, $type)
  {
    if (count($data) <= 0) {
      return $data;
    }
    foreach ($data as $key => $value) {
      $temp[$key] = $value[$filed];
    }
    array_multisort($temp, $type, $data);
    return $data;
  }

php数组array按二维排序，先按第一个字段排序，再按第二个字段排序

  /**
   * sort array by filed and type, common utility method.
   * @param array $array
   * @param string $filed1
   * @param string $type1 sort_asc or sort_desc
   * @param string $filed2
   * @param string $type2 sort_asc or sort_desc
   */
  public function sortbytwofiled($data, $filed1, $type1, $filed2, $type2)
  {
    if (count($data) <= 0) {
      return $data;
    }
    foreach ($data as $key => $value) {
      $temp_array1[$key] = $value[$filed1];
      $temp_array2[$key] = $value[$filed2];
    }
    array_multisort($temp_array1, $type1, $temp_array2, $type2, $data);
    return $users;
  }

sortmultiarray（）最多支持3维数组排序，当然可以扩充的,自定义方法重载实现对多维数字的排序，这里的多维是说数据的多个字段。

使用方法:

1. sortmultiarray（$data, [‘score' => sort_desc]）

2. sortmultiarray（$data, [‘score' => sort_desc, ‘count' => sort_asc]）

3. sortmultiarray（$data, [‘score' => sort_desc, ‘count' => sort_asc, ‘name' => sort_asc]）

/**
   * sort multi array by filed and type.
   * @param data $array
   * @param condition $array
   */
  public function sortmultiarray(&$data, $condition)
  {
    if (count($data) <= 0 || empty($condition)) {
      return $data;
    }
    $dimension = count($condition);
    $fileds = array_keys($condition);
    $types = array_values($condition);
    switch ($dimension) {
      case 1:
        $data = $this->sort1dimension($data, $fileds[0], $types[0]);
        break;
      case 2:
        $data = $this->sort2dimension($data, $fileds[0], $types[0], $fileds[1], $types[1]);
        break;
      default:
        $data = $this->sort3dimension($data, $fileds[0], $types[0], $fileds[1], $types[1], $fileds[2], $types[2]);
        break;
    }
    return $data;
  }

  public function sort1dimension(&$data, $filed, $type)
  {
    if (count($data) <= 0) {
      return $data;
    }
    foreach ($data as $key => $value) {
      $temp[$key] = $value[$filed];
    }
    array_multisort($temp, $type, $data);
    return $data;
  }

  public function sort2dimension(&$data, $filed1, $type1, $filed2, $type2)
  {
    if (count($data) <= 0) {
      return $data;
    }
    foreach ($data as $key => $value) {
      $sort_filed1[$key] = $value[$filed1];
      $sort_filed2[$key] = $value[$filed2];
    }
    array_multisort($sort_filed1, $type1, $sort_filed2, $type2, $data);
    return $data;
  }

  public function sort3dimension(&$data, $filed1, $type1, $filed2, $type2, $filed3, $type3)
  {
    if (count($data) <= 0) {
      return $data;
    }
    foreach ($data as $key => $value) {
      $sort_filed1[$key] = $value[$filed1];
      $sort_filed2[$key] = $value[$filed2];
      $sort_filed3[$key] = $value[$filed3];
    }
    array_multisort($sort_filed1, $type1, $sort_filed2, $type2, $sort_filed3, $type3, $data);
    return $data;
  }
