From: Operating system: PHP version: 5.3.2 Package: SimpleXML related Bug Type: Bug Bug description:simplexml_load_file() doesn't use HTTP headers
Description: ------------ Seen at http://stackoverflow.com/questions/2899274/ If you use simplexml_load_file() to load a remote document via HTTP, SimpleXML assumes that the content is UTF-8 regardless of the HTTP headers. In the test script below, at the time of writing, Google's web server returns something like: ------------- HTTP/1.1 200 OK Content-Type: text/xml; charset=GB2312 Date: Tue, 25 May 2010 05:05:17 GMT Pragma: no-cache Expires: Fri, 01 Jan 1990 00:00:00 GMT Cache-Control: no-cache, no-store, must-revalidate expires=Thu, 24-May-2012 05:05:17 GMT; path=/; domain=.google.com X-Content-Type-Options: nosniff Server: igfe X-XSS-Protection: 1; mode=block Transfer-Encoding: chunked <?xml version="1.0"?><xml_api_reply version="1"> <!-- single-byte encoded GB2312 stuff --> </xml_api_reply> ------------- The server advertises the content "text/xml; charset=GB2312", but since the XML declaration doesn't mention the encoding, SimpleXML assumes it is UTF-8 and eventually fails to load it. If it is at all possible, SimpleXML (and DOM, I assume) should look at the HTTP headers to find the document's encoding.
