title: removing blank spaces from email submission
body: <p>I want to create a contact form that has an email field where the user can’t enter any white space, for example: <code>test@example.com m</code><br>
  I am using a spam scrubbing function to clean user inputs.<br>
  I am using my variable like so: <code>$email = strip_tags($scrubbed['email']);</code></p>
  
  <p>How can I add something like this: <code>$email = preg_replace('/\s+/', '', $email);</code>
  to the existing <code>$email = strip_tags($scrubbed['email']);</code>?</p>
  
  <p>I tried 
  <code>$email = (preg_replace('/\s+/', '', $email)(strip_tags($scrubbed['email'])));</code> and all sorts of variations to that. They didn’t work. </p>
