我有一个这样的关联数组
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“News 1”、“News 2”等破坏了我的关联数组,并将其替换为 0,1,2...
是否有任何解决方案可以使排序保留列名?
谢谢

关于PHP多维数组(usort),我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/9483215/
