Sort a flat array of numeric strings naturally

Question

I have a bunch of numbers. Let's use these as an example: 7, 18, 24, 53, 75, 15

When I use rsort() on my array, it orders it something like this:

However, this is not what I want. I want my sorting algorithm to sort my array in numeric order descending, so that it looks like this:

What sorting algorithm is the right one? I've tried a few but none have done the trick.

There's your answer. The sorting method uses their Ascii value, which is not the same as their numerical value. You would have to convert them first. — PlamZ

Use SORT_NUMERIC flag:

rsort($myArray, SORT_NUMERIC)

Without flags, rsort (as well as sort) sorts items without changing types, i.e. strings are compared lexicographically.
