title: Disable OPCache temporarily
body: <p>I recently moved to PHP 5.4 and installed OPCache, it's very powerful!</p>
  
  <p>How can I temporarily disable the cache?</p>
  
  <p>I tried :</p>
  
  <pre><code> ini_set('opcache.enable', 0);
  </code></pre>
  
  <p>But it has no effect.</p>
  
  <p>Thanks</p>
