Trim end of string by pattern (regex?)

Question

I'm not so good at regex..

Looking for a way to trim the end of a string, if the end is:

A space followed by ONE character (can be any character)

Is preg_replace() the thing for that, or is there an easier and faster way?

The trimming will only happen once in the page

Answer 1

For just a space do this. And yes preg_replace is the way to go.

$string = preg_replace('/ .$/', '', $string);
