問題描述
我有一個看起來像這樣的數組:
<前>大批([埃里克] => 數組([計數] => 10[變化] => 1)[Morten] => 數組([計數] => 8[變化] => 1))現在，數組中的鍵是我們幫助臺系統中技術人員的姓名.我正在嘗試根據 [count] 加上 [changes] 的數量對其進行排序，然后顯示它們.我嘗試使用 usort，但隨后數組鍵被索引號替換.我該如何排序并保留數組鍵?
你應該使用 uasort 來解決這個問題.
bool uasort ( array &$array ，回調$cmp_function )
這個函數對一個數組進行排序，使得數組索引保持它們的與數組元素的相關性它們與，使用用戶定義的比較函數.這主要用于排序時關聯數組，其中實際元素順序很重要.
I have an array that looks something like this:
Array
(
[Erik] => Array
(
[count] => 10
[changes] => 1
)
[Morten] => Array
(
[count] => 8
[changes] => 1
)
)
Now, the keys in the array are names of technicians in our Helpdesk-system. I'm trying to sort this based on number of [count] plus [changes] and then show them. I've tried to use usort, but then the array keys are replaced by index numbers. How can I sort this and keep the array keys?
You should use uasort for this.
bool uasort ( array &$array , callback $cmp_function )
This function sorts an array such that array indices maintain their correlation with the array elements they are associated with, using a user-defined comparison function. This is used mainly when sorting associative arrays where the actual element order is significant.
