title: How to install YAML extension on WAMP?
body: <p>My environment is this:</p>
  
  <pre><code>Windows 7 64bit
  Wamp 2.4
  PHP 5.4.12
  </code></pre>
  
  <p>I have enabled the extension in the php.ini files at both locations viz. PHP and Apache:</p>
  
  <pre><code>extension=yaml.so
  </code></pre>
  
  <p>But <code>yaml_parse</code> is still shown as undefined.</p>
  
  <p>Any advice on how to get YAML working on Wamp?</p>
