title: how to read a cached xml file?
body: <p>have a file caching system for a php 5 library i use often.
  when the request is made i check for a cached file, if there is one i render it and exit.</p>
  
  <pre><code>$contents = file_get_contents( self::_cacheFile() );
  echo $contents;
  exit();     
  </code></pre>
  
  <p>i have to do file_get_contents instead of just include because of cached xml files with the pesky </p>
  
  <pre><code>`&lt;?xml version="1.0"?&gt;` 
  </code></pre>
  
  <p>is there a better way to pull in my cache files without shorttags firing?</p>
