前端之家收集整理的这篇文章主要介绍了
PHP多维数组排序array详解，
前端之家小编觉得挺不错的，现在分享给大家，也给大家做个参考。
PHP数组Array按字段排序
PHP;">
/**
* 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
PHP;">
/**
* 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($temp_array1,$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,‘count' => SORT_ASC,‘name' => SORT_ASC]）
PHP;">
/**
* 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,$types[0],$fileds[1],$types[1]);
break;
default:
$data = $this->sort3Dimension($data,$types[1],$fileds[2],$types[2]);
break;
}
return $data;
}
public function sort1Dimension(&$data,$data);
return $data;
}
public function sort2Dimension(&$data,$type2)
{
if (count($data) <= 0) {
return $data;
}
foreach ($data as $key => $value) {
$sort_filed1[$key] = $value[$filed1];
$sort_filed2[$key] = $value[$filed2];
}
array_multisort($sort_filed1,$sort_filed2,$data);
return $data;
}
public function sort3Dimension(&$data,$filed3,$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($sort_filed1,$sort_filed3,$type3,$data);
return $data;
}
