hah.. I should have mentioned this as well, but my brain is absorbed in... sockets... and xml.. and sending headers manually via fputs.. nothing relative to this discussion at all.. hah..
<?php
$_XML_DATA = "<xmlGoesHere></xmlGoesHere>\r\n";
$_FULL_XML_REQUEST = "<?xml version=\"1.0\" encoding=\"UTF-8\"?>\r\n";
$_FULL_XML_REQUEST .= "<!DOCTYPE REQUEST_GROUP SYSTEM \"SomeXMLdtd.dtd\">\r\n";
$_FULL_XML_REQUEST .= $_XML_DATA;
$_XML_REQUEST_HEADER = "POST /path/to/script.php HTTP/1.1\r\n";
$_XML_REQUEST_HEADER .= "Host: my.server.com\r\n";
$_XML_REQUEST_HEADER .= "Content-type: application/x-www-form-urlencoded\r\n";
$_XML_REQUEST_HEADER .= "Content-length: " . strlen($_FULL_XML_REQUEST) . "\r\n";
$_XML_REQUEST_HEADER .= "Connection: close\r\n\r\n";
$fp = fsockopen("my.server.com", 80, &$_FSOCK_ERR_NUMBER, &$_FSOCK_ERR_MESSAGE, 100);
~
if(!$fp){
exit("Failed to open socket...");
}
if (fputs($fp, $_XML_REQUEST_HEADER . $_FULL_XML_REQUEST) === FALSE) {
exit("Failed to send request...");
}
while(!feof($fp)){
~
// "@" error suppression used on fgets() due to bug in PHP that reports the following waring:

// No good solution found online, most people adjust their error reporting to ignore warnings (sloppy!)
$tmp = @fgets($fp, 4096);
$_XML_RESPONSE .= $tmp;
}
echo "<pre>\n";
echo $_XML_RESPONSE;
fclose($fp);

Or use sockets...

Just don't send any HTTP headers.
