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.
原文链接：https://www.f2er.com/php/138831.htmlforeach ($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
