Oh yeah - not sure if spaces are considered alphanumeric or not, but I need to keep spaces - replacing anything that is NOT a letter, a number or a space. Thanks again. -----Original Message----- From: Ben Miller [mailto:biprellim@xxxxxxxxx] Sent: Friday, June 05, 2009 2:09 AM To: php-general@xxxxxxxxxxxxx Subject: preg_replace I bought PHP & MySQL for DUMMIES and it shows me how to use special characters for pattern matching and I've figured out the basics of using preg_replace to replace pattern matches. What I am having trouble with, though, is figuring out how to replace anything that does not match the pattern. For example, I want to replace anything that is NOT an alphanumeric character. Any help would be appreciated. Thanks.
