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; }
