Re: sort string beginning at index?

Stan McCann said the following on 29/09/2005 19:43:
I need some recommendations as to how to go about sorting a string not from the beginning of the string, but from a given index into the string. I am reading a data file into an array using file(), then looping through the string which contains fields seperated by |. Do I have to explode each individual record to sort them using array_multisort()? What I was hoping for was something like sort
($array, SORT_STRING, 15) where 15 is the index into the string to sort on instead of starting at 0. I've been digging through the docs reading about sort and usort and the others but nothing looks like it will work short of using up time and memory creating a multidimensional array to sort.

Well, manipulating data in an array/other data structure is far easier than trying to do it in-place in a concatenated string.

I would highly recommend exploding it into an array and sorting the array.
