[Moderators: This is not a bug report :P] If you're using $data = http_get('http://...'); to get your message and you're getting weird numbers in it, PLEASE see tac at smokescreen dot org's message below! Note that the body element http_parse_message returns is NOT the page's contents of the <body> tag! It's just the page content as seen by a browser, what wget would retrieve, what file_get_contents('http://...') would output, etc. -dav7

To change the request protocol use the option "protocol". The allowed values are: * HTTP_VERSION_NONE (integer) * HTTP_VERSION_1_0 (integer) * HTTP_VERSION_1_1 (integer)

The hard work of parsing out the response is done in http_parse_message(). To replace the relatively weak file_get_contents(), using $body = http_parse_message(http_get($url))->body; The advantages to using http_get include getting back headers and controlling timeouts.
