I want to create a contact form that has an email field where the user can't enter any white space in the field, for example: test@ex ample.com I am using a spam scrubbing function taught to us in the book to clean user inputs. I am using my variable like so. $email = strip_tags($scrubbed['email']); how can I add something like this $email = preg_replace('/\s+/', '', $email); to the existing $email = strip_tags($scrubbed['email']); I tried $email = (preg_replace('/\s+/', '', $email)(strip_tags($scrubbed['email']))); and all sorts of variations to that. it doesn't work.
