title: PHP - url path as parameters
body: <p>I'm using PHP for creating websites. 
  To change the content of the page, there is script which includes different files based on a URL parameter, eg. <code>http://example.com/index.php?page=news</code>. 
  This loads some news page. When I want to load an exact article, I add another parameter like this:  <code>http://example.com/index.php?page=news&amp;id=18964</code>,
  but it does not look nice.<br>
  I want to have my URLs look like they are on this website: <code>http://stackoverflow.com/questions/ask</code>,
  or in my case:  <code>http://example.com/news/18964</code>.  </p>
  
  <p>I would look on google, but I don't know what to search for. </p>
