问题描述
我有这样的阵列
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
)

}
我希望能够通过距离哈希数组排序。帮帮我!非常感谢
I want to be able to sort the arrays in the hash by distance. HELP! Thanks a lot
推荐答案
您需要先提取所有的距离,然后通过二者的距离和数据的功能。如例3在在array_multisort 文档中
You need to extract all the distances first, then pass both the distance and the data to the function. As shown in example 3 in the array_multisort documentation.
foreach ($data as $key => $row) {
$distance[$key] = $row['distance'];
}
array_multisort($distance, SORT_ASC, $data);
此假设你想在最短的距离第一次,否则修改 SORT_ASC
到 SORT_DESC
This assumes you want the shortest distances first, otherwise change the SORT_ASC
to SORT_DESC
