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，先按第一個字段排序，再按第二個字段排序
/**
* 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 $users;
}
sortMultiArray（）最多支持3維數(shù)組排序，當(dāng)然可以擴充的,自定義方法重載實現(xiàn)對多維數(shù)字的排序，這里的多維是說數(shù)據(jù)的多個字段。
使用方法:
1. sortMultiArray（$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)
