Replace all multispace characters with a single space EXCEPT the newline character

Question

The title is self explanatory.

Currently I use preg_replace('/\s+/', ' ',$row['message']); but this removes newline characters as well, but I want to preserve them.

Use a double negated class, and negate \n. This is the perfect case to use regex-negation!

preg_replace('/[^\S\n]+/', ' ', $row['message']);

Here is a regex demo.

@AvinashRaj That is correct! Or you can use `[[:blank:]]+` – Unihedron Sep 25 '14 at 14:44
