HTTPS Request & XML

PHP
1

Dear Gurus,

i am trying to connect to a remote Server via https and fire some XML commands. how cal i do it. the following are the steps:

Step 1. URL
https://IP:894/Receiver?CODE=GW&LOGIN=username&PASSWORD=je0b12221a0558c&SOURCE_TYPE=EXT&SERVICE_PORT=200

Step 2. XML
<?xml version=“1.0”?><COMMAND><TYPE>EXRCTRFREQ</TYPE><DATE>12/03/13</DATE><EXTNWCODE>ZM</EXTNWCODE><MSISDN>9936574991</MSISDN><EXTREFNUM></EXTREFNUM><MSISDN2>9798144059</MSISDN2><AMOUNT>1</AMOUNT><SELECTOR>1</SELECTOR></COMMAND>

How can this be done. this is what i came up with but am stuck with pass the URL GET parameter.

<?php
$site = "IP:894";
$loc = "Receiver?CODE=GW&LOGIN=username&PASSWORD=je0b12221a0558c&SOURCE_TYPE=EXT&SERVICE_PORT=200";

$BODY = "<?xml version=\\"1.0\\"?>
<COMMAND>
<TYPE>EXRCTRFREQ</TYPE>
<DATE>12/03/13</DATE>
<EXTNWCODE>ZM</EXTNWCODE>
<MSISDN>9936574991</MSISDN>
<EXTREFNUM></EXTREFNUM>
<MSISDN2>9798144059</MSISDN2>
<AMOUNT>1</AMOUNT>
<SELECTOR>1</SELECTOR>
</COMMAND>
";

echo $out=XML_request($site,$loc,$BODY);

function XML_request($site, $location, $data){
        $site = explode(':', $site);
        if(isset($site[1]) and is_numeric($site[1])){
                $port = $site[1];
        }else{
                $port = 80;
        }
        $return='';
        $site = $site[0];

		$conn = fsockopen ("ssl://".$site, $port,$errno,$errstr,30); #open the connection
        if(!$conn){ #if the connection was not opened successfully
                $response="Issues";
        }else{
            fputs($conn, $data);

            #socket_set_blocking ($conn, false);
            $response = "";
            while(!feof($conn)){
                $response .= fgets($conn, 1024);
            }
            $return=$response;
            fclose($conn);
        }
	return $return;
}



?>
