POST xml WITHOUT using CURL

[poestpo]

I need to POST xml data without CuRL.there are a LOT of snippets, but nothing seems to work. The latest attempt:\[code\]function salesOrder($xml, $url){ $context = stream_context_create(array( 'http' => array( 'method' => 'POST', 'header' => "Content-type: application/xml\r\n", 'content' => $xml, 'timeout' => 5, ), )); $ret = file_get_contents($url, false, $context); return false !== $ret;}\[/code\]returns nothing, blank page.I have tried http://wezfurlong.org/blog/2006/nov/http-post-from-php-without-curl/The problem is I dont really understand it and i can not seem to find a good tutorial that covers this problem. Can anyone point me in the right direction?
