Simon, you were exactly right. I made the mistake of referring to the Partner API in the web link instead of the Enterprise API. That solved the problem and I can now access values from the query result.

For the benefit of others using PHP5, I'm enjoying some success integrating with SForce. I'm using PHP 5.0.4 with PHP's built-in SOAP module, so the SalesForceClient toolkit is not necessary.

Here's some sample PHP code I use from a web link (that happens to be on an Account). I pass the session, (Enterprise API) endpoint and username in the link.

** Take the space out of the initial PHP tag: < ?php should not have a space. HTML tags get whacked by this forum unfortunately.


< ?php
// QUERY THE USER TABLE IN SALESFORCE

// Establish a connection back to SFDC
$SESSION = $_GET['session'];
$ENDPOINT = $_GET['endpoint'];
$USERNAME = $_GET['username'];

// +----------------------------------------------------------------------+
// | ACCESS SALESFORCE.COM USING THE SUPPLIED SESSION AND ENDPOINT
// +----------------------------------------------------------------------+
$wsdl = "file://E:/webroot/sfdc/enterprise.wsdl.xml";
// The trace paramenter, below, enables examination of the SOAP messages
// using __getLastRequest and __getLastResponse
$client = new SoapClient( $wsdl , array('trace' => 1) ) ;
$client->__setLocation($ENDPOINT);
$sessheader = new SoapHeader('urn:enterprise.soap.sforce.com', 'SessionHeader',
(object) array('sessionId'=>$SESSION), 0);


// Lookup the userid
$user = array('type'=>'user'); // In this case, this doesn't matter because getUserInfo doesn't take any paramenters, but the __soapCall requires an array.
// In the next line, use __soapCall so you can pass the session header variable
$getUserInfoResult = $client->__soapCall('getUserInfo', array((object) $user) , NULL,
$sessheader, $ohdrs);
$userId = $getUserInfoResult -> result -> userId ;
// echo "userid: $userId";


// Lookup user's address, phone, etc.
$query = "Select Id, Username, LastName, FirstName, Street, City, State, PostalCode, Email, Phone FROM User WHERE Id = '$userId'";
// In the next line, we establish queryString as the parameter to pass, according
// to the wsdl. You can easily see the functions using $client->__getFunctions()
$query_array = array( 'queryString' => $query );
$queryResult = $client->__soapCall('query', array((object) $query_array) , NULL,
$sessheader, $other_headers );

// Access the records contained in the result.
$records = $queryResult->result->records;

// Since the result has exactly one record, I don't need to
// iterate through multiple records and can access the values directly.
echo "LastName: ".$records->LastName."
";
echo "Street: ".$records->Street."
";
