PHP double sort array based on substring
arrays, cisco, php
Solution
You can use the flag while using asort(), like below.
asort($arr, SORT_NATURAL | SORT_FLAG_CASE);print_r($arr);
It will print/sort the data as yo need.
Problem
I am building a custom switch manager for work, my current issue is more an aesthetic one but I think it is a good learning experience. I have posted the array below for clarity: ``` Array ( [1] => FastEthernet0/1 [10] => FastEthernet0/10 [11] => FastEthernet0/11 [12] => FastEthernet0/12 [13] => FastEthernet0/13 [14] => FastEthernet0/14 [15] => FastEthernet0/15 [16] => FastEthernet0/16 [17] => FastEthernet0/17 [18] => FastEthernet0/18 [19] => FastEthernet0/19 [2] => FastEthernet0/2 [20] => FastEthernet0/20 [21] => FastEthernet0/21 [22] => FastEthernet0/22 [23] => FastEthernet0/23 [24] => FastEthernet0/24 [3] => FastEthernet0/3 [4] => FastEthernet0/4 [5] => FastEthernet0/5 [6] => FastEthernet0/6 [7] => FastEthernet0/7 [8] => FastEthernet0/8 [9] => FastEthernet0/9 [25] => Null0 ) ``` On our bigger switches I am using `asort($arr);` to get GigabitEthernet1/1 to come before 2/1, etc... My goal is to sort on the interface number (part after '/') so that 1/8 comes before 1/10. Could someone point me in the right direction, I want to work for the results but I am not familiar enough with PHP to know exactly where to go. Notes: On out larger multi-module switches the IDs are not in order so a sort on $arr[key] won't work.
