Hey Ben,
to replace everything thats not alphanumeric, use the following statement:
$output = preg_replace('/[^[:alnum:]]/', '', $input);

PS: Spaces are not alphanumeric ;)

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.

Subject: [PHP] 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.
Ben
