PHP数组Array按字段排序/***Sortarraybyfiledandtype,commonutilitymethod.*@paramarray$data*@paramstring$sort_filed*@

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;
 }
