title: How can I include the period (.) in Vim's search and replace command? (replacing .html extensions)?
body: <p>When I do: <code>/.html</code> Vim looks for <code>html</code></p>
  
  <p>I would like to replace all the <code>.html</code> with <code>.php</code></p>
  
  <p>Something like this: <code>:%s/html ext/php ext/g</code></p>
