zero results when using php and nuSoap library.

[ajpug]

If I run the java example that comes with the APIs I get results, however, if I try to use a simple php script I get zero results.
I use the following code:
<?php
/**
* This set of functions queries Google Search API.
*
* This is a single php page and set of functions that, when given the right
* data will return a set of formatted Google search results. Requires NuSOAP,
* located at
[sourceforge.net...]

* @author: Mike Papageorge,
error_reporting(E_ALL);
// Variables for the search. You need to edit these to use this:

$id = 'YourAppKeyHere';
$site = 'www.YourSiteHere.com';
$baseurl = 'http://api.google.com/search/beta2'; // Googles API URI
$form = '
<form action="'.$_SERVER['PHP_SELF'].'" method="get">
<label for="p">Search Terms</label>
<input name="p" id="p" type="text" />
<input type="submit" value="search" />
</form>

';

/**
* A little 'controller' to make this sample page work:
*
*/
$xhtml = '';
if(isset($_GET['p']) && $_GET['p']!= '') {
$data = getResultArray($id, $site, $baseurl);
$xhtml = $form.formatGoogleResultset($data);
} else {
// If an empty search was given:
$xhtml = (isset($_GET['p']) && $_GET['p'] == '')? '<p>Please enter a search term</p>':'';
// Show the form:
$xhtml .= $form;
}

echo $xhtml;

//
//
//Here be functions....
//
//

/**
* Build an array with the parameters we want to use.
*
*/
function setParams($id, $site) {
$params = array(
// Details for all of these can be found in the developer's kit,
// on this page: APIs_Reference.html
'key' => $id,
'q' => "site:$site $_GET[p]",
'start' => 0,
'maxResults' => 10,
'filter' => true,
'restrict' => '',
'safeSearch' => true,
'lr' => 'lang_enŠlang_fr',
'ie' => '',
'oe' => ''
);
return $params;
}

/**
* This function passes our data to NuSOAP, and
* returns the search results:
*/

function getResultArray($id, $site, $baseurl) {
// Get the parameters:
$params = setParams($id, $site);
// Include the library:
include_once("libs/nusoap/nusoap.php");
// Create a instance of the SOAP client object
$soapclient = new soapclient($baseurl);
$data = $soapclient->call("doGoogleSearch", $params,
"urn:GoogleSearch", "urn:GoogleSearch");
return $data;
}

/**
* This function formats our Google specific array:
*
*/
function formatGoogleResultset($data) {
// If no results were found:
if($data['estimatedTotalResultsCount'] == 0) {
$results = '<p>There were 0 results found with Google search. Please try again by typing your search terms into the search box, and then click search.</p>';
return $results;
}

// Now down to business:
$tmp = '';
foreach($data['resultElements'] as $value) {
$tmp .= '<dt><a href="'.$value['URL'].'">'.$value['title'].'</a></dt>';
$r = htmlentities($value['snippet']);
$tmp .= '<dd>'.$r.'</dd>

';
}
// Here we say how many results were found, keep in mind you will need to add pagination to see them all:
$results = '<h1>These 10 results of '.$data['estimatedTotalResultsCount'].' provided by Google search.</h1>
<dl>
'.$tmp.'
</dl>';

return $results;
}

?>

Any idea?
Thanks a lot.
