PHP多維數(shù)組排序array詳解

更新時(shí)間：2017年11月21日 17:15:32 作者：Stephen102

這篇文章主要為大家詳細(xì)介紹了PHP多維數(shù)組排序array的相關(guān)資料，具有一定的參考價(jià)值，感興趣的小伙伴們可以參考一下

PHP數(shù)組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數(shù)組Array按二維排序，先按第一個(gè)字段排序，再按第二個(gè)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維數(shù)組排序，當(dāng)然可以擴(kuò)充的,自定義方法重載實(shí)現(xiàn)對(duì)多維數(shù)字的排序，這里的多維是說數(shù)據(jù)的多個(gè)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;
  }
