title: PHP strlen question
body: <p>Ok I am checking that a string is at least 4 characters long and 25 or less characters short</p>
  
  <p>I tried to use strlen like this</p>
  
  <pre><code>$userNameSignupLength = strlen($userNameSignup);
  
  else if($userNameSignupLength&lt;4 &amp;&amp; $userNameSignupLength&gt;25) {
  
              $userNameSignupError = "Must be between 4 to 25 characters long";
  
          }
  </code></pre>
  
  <p>but it doesn't work... what did I do wrong?</p>
