PHP和XML - 如何使用此XML在PHP中生成soap请求？

Question

I am completly new to SOAP operations.

I have been provided with an XML document (SOAP) to get some collection points for a shipping method.

From the manual located here:

http://privpakservices.schenker.nu/package/package_1.3/packageservices.asmx?op=SearchCollectionPoint

I can see that I need to use the following SOAP request:

POST /package/package_1.3/packageservices.asmx HTTP/1.1
Host: privpakservices.schenker.nu
Content-Type: text/xml; charset=utf-8
Content-Length: length
SOAPAction: "http://privpakservices.schenker.nu/SearchCollectionPoint"

<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
  <soap:Body>
    <SearchCollectionPoint xmlns="http://privpakservices.schenker.nu/">
      <customerID>long</customerID>
      <key>string</key>
      <serviceID>string</serviceID>
      <paramID>int</paramID>
      <address>string</address>
      <postcode>string</postcode>
      <city>string</city>
      <maxhits>int</maxhits>
    </SearchCollectionPoint>
  </soap:Body>
</soap:Envelope>

The thing is that i don't know how to send this as a request using PHP, and how to get the response.

Any help to pinpoint me in the right direction, is much appreciated.

UPDATE

I can read the response data with var_dump. However, I am not able to read individual element data.

I need to read data as below

foreach($parser as $row) {
  echo $row->customerID;
  echo $row->key;
  echo $row->serviceID;  
}

If anyone should be interested, i have provided the correct answer:

$soapUrl = "http://privpakservices.schenker.nu/package/package_1.3/packageservices.asmx?op=SearchCollectionPoint";

$xml_post_string = '<?xml version="1.0" encoding="utf-8"?><soap12:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope"><soap12:Body><SearchCollectionPoint xmlns="http://privpakservices.schenker.nu/"><customerID>XXX</customerID><key>XXXXXX-XXXXXX</key><serviceID></serviceID><paramID>0</paramID><address>RiksvŠgen 5</address><postcode>59018</postcode><city>Mantorp</city><maxhits>10</maxhits></SearchCollectionPoint></soap12:Body></soap12:Envelope>';

$headers = array(
"POST /package/package_1.3/packageservices.asmx HTTP/1.1",
"Host: privpakservices.schenker.nu",
"Content-Type: application/soap+xml; charset=utf-8",
"Content-Length: ".strlen($xml_post_string)
); 

$url = $soapUrl;

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $xml_post_string);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

$response = curl_exec($ch); 
curl_close($ch);

$response1 = str_replace("<soap:Body>","",$response);
$response2 = str_replace("</soap:Body>","",$response1);

$parser = simplexml_load_string($response2);
