sorting csv strings

[g00fy_m]

hey to all,

i have a file of string that are collected from user input, in the form

"first string", "second string", "third strind"

there is only ever 3 strings per line of the file

i would like to be able to sort all strings on a per value basis, that is i would like all strings to be sorted by say string 2

is this a job for multi_sort, after i dump it into a matrix ??

i had a quick fiddle but couldnt get it to work.

any ideas would be great

thanx in advance

Assuming you dump it into an array of arrays, with each of the three strings being an element of the sub-array, you can use [man]usort[/man] to sort the outer array. You just need to define a comparison function to compare the sub-arrays based on the correct element.
