title: Enable OPCache not working in WAMP
body: <p>I tried to enable OPCache for Drupal 8.0.4 in WAMP 3 but it isn't working. So I googled and changed a few things in my php.ini file and here is what I changed:</p>
  
  <pre><code>opcache.enable=0
  </code></pre>
  
  <p>to</p>
  
  <pre><code>opcache.enable=1
  </code></pre>
  
  <p>and also</p>
  
  <pre><code>opcache.enable_cli=0
  </code></pre>
  
  <p>to</p>
  
  <pre><code>opcache.enable_cli=1
  </code></pre>
  
  <p>But still, the '!' mark appears near the PHP Extension. When I try to get the log it says :</p>
  
  <pre><code>Sorry,
  
  The 'php_opcache' extension cannot be loaded by 'extension=php_opcache.dll' in php.ini. Must be loaded by 'zend_extension='.
  
  Switch cancelled
  
  Press ENTER to continue...
  </code></pre>
  
  <p>But in the PHP.ini file it says:</p>
  
  <pre><code>zend_extension ="C:/wamp/bin/php/php7.0.0/ext/php_opcache.dll"
  </code></pre>
  
  <p>What else should I do to enable OPCache?</p>
