cool, glad you got it working...if you think there's a bug with using / and | you might want to see if you can replicate the problem, and if its really a bug, submit it...my guess is that it was just a typo or something

The only thing I changed was using / delimiters instead of | delimiters in the search string. No idea if/why that would affect anything in the replacement string. Anyway, I finally came up with exactly what I wanted: preg_replace(array("/\s*\n+\s*/", "/[ ]+/"), array("\n", " "), $input); All padding (defined as any series of spaces, newlines and sometimes tabs) is removed from $input, but always leaving at least a space or a newline in its place. If there were any newlines in the "padding", then a newline is left. If there weren't, then a space is left. Thanks for the help!
