title: How to avoid $_GET browser blocking because of XSS?
body: <p>I'm palying out with ebay api. Trying to create my "local" xml because it doesn't allow me to read it from remote website because of XSS. </p>
  
  <p>It all works fine if I write complete url to ebay api in file_get_contents() , but if I try to manipulate variables through $_GET it stops working because browser don't allow it. Any idea how could I avoid this? 
  This is what I get in firebug</p>

  <p>Here's the code </p>
  
  <pre><code>&lt;?php
  header("Content-type: text/xml; charset=utf-8"); 
  $a= $_GET["storename"];
  $b= $_GET["catnumber"];
  
  echo file_get_contents('http://svcs.ebay.com/services/search/FindingService/v1?OPERATION-NAME=findItemsIneBayStores&amp;SERVICE-VERSION=1.0.0&amp;SECURITY-APPNAME=APPID&amp;RESPONSE-DATA-FORMAT=XML&amp;REST-PAYLOAD&amp;storeName='. $a . '&amp;outputSelector=categoryId='. $b);
