title: easy: iframe inside string
body: <p>I have a code I think is very hard, but I cannot figure out how to solve it.</p>
  
  <p>I need the iframe working, but doesn't find a way to read it as a code instead of text inside the string...</p>
  
  <pre><code>&lt;div class="tab-pane" id="mounting"&gt;
      &lt;h1&gt;Mounting&lt;/h1&gt;
      &lt;?php
      $a = strtolower($title);
      if (strpos($a, 'vw') !== false){
          if (strpos($a, 'brake disc') !== false){ 
              echo '&lt;iframe width="560" height="315" src="https://www.youtube.com/embed/QuyfFY4cvww" frameborder="0" allowfullscreen&gt;&lt;/iframe&gt;';
          }
      }
      ?&gt;
  &lt;/div&gt;
