PHP数组多个字段分别排序

2017-04-27 14:43

1. PHP数组Array按其中一个字段排序

/**
* 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;
}

2.PHP数组Array2个字段排序,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;
}

3. 扩展方法sortMultiArray()最多支持对数组3个字段排序,当然可以扩充的,自定义方法重载实现对多维数字的排序。

使用方法:

  • sortArrayMultiFields($data, [‘score’ => SORT_DESC])

  • sortArrayMultiFields($data, [‘score’ => SORT_DESC, ‘count’ => SORT_ASC])

  • sortArrayMultiFields($data, [‘score’ => SORT_DESC, ‘count’ => SORT_ASC, ‘name’ => SORT_ASC])

  • /**
     * Sort multi array by filed and type.
     * @param data $array
     * @param condition $array
     */
    public function sortArrayMultiFields(&$data, $condition)
    {
        if (count($data) <= 0 || empty($condition)) {
            return $data;
        }
        $fieldsCount = count($condition);
        $fileds = array_keys($condition);
        $types = array_values($condition);
        switch ($fieldsCount) {
            case 1:
                $data = $this->sort1Field($data, $fileds[0], $types[0]);
                break;
            case 2:
                $data = $this->sort2Fields($data, $fileds[0], $types[0], $fileds[1], $types[1]);
                break;
            default:
                $data = $this->sort3Fields($data, $fileds[0], $types[0], $fileds[1], $types[1], $fileds[2], $types[2]);
                break;
        }
        return $data;
    }
    
    public function sort1Field(&$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 sort2Fields(&$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 sort3Fields(&$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;
    }
