title: adding white space between clean string functions
body: <p>I've got the following code which outputs two different strings sent from a php contact form.</p>
  
  <pre><code>$email_message .= "Module: ".clean_string($modcode_1_from)."\s".clean_string($modcode_2_from)."\r\n";
  </code></pre>
  
  <p>is meant to display module code 1 and module code 2.</p>
  
  <p>Currently looks likes this</p>
  
  <p>1001\s2002</p>
  
  <p>However i want it to look like:</p>
  
  <p>1001 2002</p>
  
  <p>So i added \s to add white space between the strings but it does not do anything for me.</p>
