I am trying to sort an array.

I have an array of data, where each line represents a new index in the array. I need to sort it descending, by the first number.

My array:

7[^.^]username[^.^]idnumber[^.^]State[^.^]
13[^.^] username[^.^] idnumber[^.^] State[^.^]
9[^.^] username[^.^] idnumber[^.^] State[^.^]
19[^.^] username[^.^] idnumber[^.^] State[^.^]

ksort and asort kind of work, but it recognizes a “9” as being bigger than “81”, so it would return the following:

13[^.^] username[^.^] idnumber[^.^] State[^.^]
19[^.^] username[^.^] idnumber[^.^] State[^.^]
7[^.^]username[^.^]idnumber[^.^]State[^.^]
9[^.^] username[^.^] idnumber[^.^] State[^.^]

I know I need some kind of custom sort, but I’m not sure how. Thanks.

    All PHP sort() functions can take sort_flags as their second argument. Try using SORT_NUMERIC:

    sort($myArray, SORT_NUMERIC);

    Or use usort() for a custom sorting callback
