Re: preg_replace

Hey Ben, to replace everything thats not alphanumeric, use the following statement: $output = preg_replace('/[^[:alnum:]]/', '', $input); Greetings from Germany Marc PS: Spaces are not alphanumeric ;) Ben Miller wrote:

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.

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. Ben
