我有一个像这样的关联数组
Array
(
["News 1"] => Array
(
[text] => tests
[language] =>
[advertiserCompetitionScale] => 5
[avgSearchVolume] => 7480000
[lastMonthSearchVolume] => 9140000
)
["News 2"] => Array
(
[text] => personality tests
[language] =>
[advertiserCompetitionScale] => 5
[avgSearchVolume] => 165000
[lastMonthSearchVolume] => 201000
)
["News 3] => Array
(
[text] => online tests
[language] =>
[advertiserCompetitionScale] => 5
[avgSearchVolume] => 246000
[lastMonthSearchVolume] => 301000
)
)
我设法按我想要的列对其进行排序(例如 LastMonthSearchVolume)
// compare function
function cmpi($a, $b)
{
return strcmp($a["lastMonthSearchVolume"], $b["lastMonthSearchVolume"]);
}
// do the array sorting
usort($latest_array, 'cmpi');
问题是当我转储数组以查看结果时,usort 通过删除“新闻 1”、“新闻 2”等破坏了我的关联数组。并将其替换为 0、1、2 ......
有什么解决方案可以让 sort 保留列名吗?
谢谢
