title: How to Add .php extension to Category pages in Wordpress
body: <p>I am hosting a Wordpress site at the Rackspace Cloud.  The main site is written in <strong>ASP.NET</strong> so I have the default technology set to <strong>ASP.NET/IIS</strong>.</p>
  
  <p>Php files can still be executed in this environment, however they need to end in a <code>.php</code> extension so the server knows how to process them.</p>
  
  <p>I have found a way to add the <code>.php</code> extension to permalinks by just adding the <code>.php</code> to the end of the structure. I also have found a way to add it to any pages with this plugin, <a href="http://wordpress.org/extend/plugins/html-on-pages/" rel="nofollow noreferrer">http://wordpress.org/extend/plugins/html-on-pages/</a>.</p>
  
  <p>It appears all I have left are <strong>Category</strong> and <strong>Tag</strong> pages.
  For example <code>[domain]/category/uncategorized</code>.</p>
  
  <p>I'd like to change this to <code>/category/uncategorized/index.php</code> or simply <code>[domain]/category/uncategorized.php</code></p>
  
  <p>One other thing to note, if you're not familiar with the Rackspace Cloud, I can not use a <code>.htaccess</code> file for this.</p>
  
  <p>I would think there is somewhere I can do this within the code of Wordpress application, but I am not a php developer and have no idea where I would start.</p>
