title: In PHP how can you clear a WSDL cache?
body: <p>In through <code>php_info()</code> where the WSDL cache is held (<code>/tmp</code>), but I don't necessarily know if it is safe to delete all files starting with WSDL. </p>
  
  <p>Yes, I <em>should</em> be able to just delete everything from <code>/tmp</code>, but I don't know what else this could effect if I delete any all WSDL files.</p>
