我有这个阵列
- Array
- (
- [0] => Array
- (
- [brand] => blah blah
- [location] => blah blah
- [address] => blah blah
- [city] => blah blah
- [state] => CA
- [zip] => 90210
- [country] => USA
- [phone] => 555-1212
- [long] => -111
- [lat] => 34
- [distance] => 3.08
- )
- [1] => Array
- (
- [brand] => blah blah
- [location] => blah blah
- [address] => blah blah
- [city] => blah blah
- [state] => CA
- [zip] => 90210
- [country] => USA
- [phone] => 555-1212
- [long] => -111
- [lat] => 34
- [distance] => 5
- )
- .
- .
- .
- }
我希望能够按距离对哈希中的数组进行排序.救命！非常感谢
您需要先提取所有距离,然后将距离和数据传递给函数.如
array_multisort文档中的示例3所示.
- foreach ($data as $key => $row) {
- $distance[$key] = $row['distance'];
- }
- array_multisort($distance,SORT_ASC,$data);
这假设您首先需要最短距离,否则将SORT_ASC更改为SORT_DESC
