title: Syntax error on return statement
body: <p>I'm doing this simple website, and I have run into this error:</p>
  
  <p>My function:</p>
  
  <pre><code>&lt;?php 
  function user_exists($username)
  {
      $username = sanitize($username);
      $query = mysqli_query($connect, "SELECT COUNT(`user_id`) FROM `users` WHERE `username` = '$username'");
      return (mysqli_result($query, === 0) 1) ? true : false;
  }
   ?&gt;
  </code></pre>
  
  <p>My php error log:</p>
  
  <pre><code>PHP Parse error:  
  syntax error, unexpected '===' (T_IS_IDENTICAL) in function on line 6
  </code></pre>
  
  <p>Line 6 is the return line.</p>
  
  <p>I understand what a syntax error means, but I'm quite sure that the <code>'==='</code> is not the problem.</p>
