PHP get data from soap service - php

Question

I need to get data from http://ws.jrtwebservices.com/jrtlowfaresearch/jrtlfs.asmx, this service need credential information.such as ID, userid and system value. I put these information into one string:
$xml_post_string = "<POS><Source> <RequestorID Type='21' ID='xxx'/> </Source> <TPA_Extensions> <Provider><System>xxx</System> <Userid>xxx</Userid> </Provider></TPA_Extensions></POS>"
And i also defined SoapClient:
$client = new SoapClient(null, array('uri' => "http://ws.jrtwebservices.com",
'location => "http://ws.jrtwebservices.com/jrtlowfaresearch/jrtlfs.asmx") );
I call soapCall as:
$response = $client->__soapCall('do_LowfareSearch',array($xml_post_string),array('soapaction' => 'http://jrtechnologies.com/do_LowfareSearch'));
Does anybody know why i get empty response?
Thanks very much!

Using your code, the request looks like this:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xm...">
<SOAP-ENV:Body>
<ns1:do_LowfareSearch>
<param0 xsi:type="xsd:string">
"<POS><Source> <RequestorID Type='21' ID='xxx'/> </Source> <TPA_Extensions> <Provider <System>xxx</System> <Userid>xxx</Userid> </Provider></TPA_Extensions></POS>"
</param0>
</ns1:do_LowfareSearch>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
The client used the method you passed but could not structure the parameters the way you gave them. All of your parameters are just in " " inside of <param0>.
(Also, you are missing a ' after location. 'location => "http:...)
When you make your SOAP client you want to set the WSDL, it will do all the XML formatting for you.
The WSDL should have the location in it so you do not need to worry about that.
I like to use a WSDL validator to test out the methods and see their parameters.
You should structure the information you want to pass as arrays or a classes and let the SOAP client and WSDL convert it into the XML you need.
So something like this is what you are looking for:
<?php
//SOAP Client
$wsdl = "http://ws.jrtwebservices.com/jrtlowfaresearch/jrtlfs.asmx?WSDL";
$client = new SoapClient($wsdl, array( 'soap_version' => SOAP_1_1,
'trace' => true, //to debug
));
try {
$args = array(
'companyname'=> 'xxx',
'name'=> 'xxx',
'system'=> 'xxx',
'userid'=> 'xxx',
'password'=> 'xxx',
'conversationid'=>'xxx',
'entry'=> 'xxx',
);
$result = $client->__soapCall('do_LowfareSearch', $args);
return $result;
} catch (SoapFault $e) {
echo "Error: {$e}";
}
//to debug the xml sent to the service
echo($client->__getLastRequest());
//to view the xml sent back
echo($client->__getLastResponse());
?>
