title: Is there a way to catch an Exception without having to create a variable?
body: <p>In PHP, I sometimes catch some exceptions with try/catch :</p>
  
  <pre><code>try {
      ...
  } catch (Exception $e) {
      // Nothing, this is normal
  }
  </code></pre>
  
  <p>With that kind of code, I end up with the variable <code>$e</code> that is created for nothing (lots of resources), and PHP_MD (PHP Mess Detector) creates a warning because of an unused variable.</p>
