If you know the web services API, you just send your request.  It 
shouldn't matter whether you're using Java, PHP, Python, even VB or even 
Telnet to generate your request -- most web services accept an HTTP POST 
message consisting of XML code which is used to perform some kind of 

There are two things you can do -- either use the cURL functions (your 
PHP binary must be compiled with cURL enabled to do this), which give 
you an advanced set of URL accesses, or open a socket to the remote 
machine with the web service and send a stream of POST data that way.  
You can use Rasmus Lerdorf's "postToHost" function (this may as well 
just become a PHP function, it gets referenced so much), which I have 
appended to this message.

Either way, just generate your XML string and fire it at the remote 
machine.  You will need to write code to handle the response, obviously.

function PostToHost($host, $path, $data_to_send)
        $fp = fsockopen($host,80);
        fputs($fp, "POST $path HTTP/1.0\n");
        fputs($fp, "Host: $host\n");
        fputs($fp, "Content-type: application/x-www-form-urlencoded\n");
        fputs($fp, "Content-length: " . strlen($data_to_send) . "\n");
        fputs($fp, "Connection: close\n\n");
        fputs($fp, $data_to_send);
        while(!feof($fp)) {
                echo fgets($fp, 128);
