這篇文章主要為大家詳細介紹了PHP多維陣列排序array的相關資料,具有一定的參考價值,感興趣的小夥伴們可以參考一下

PHP數組Array按欄位排序

  /**   * 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數組Array按二維排序,先按第一個欄位排序,再按第二個欄位排序

  /**   * 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()最多支援3維數組排序,當然可以擴充的,自訂方法重載實現對多維數位排序,這裡的多維是說資料的多個欄位。

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;  }
