Google Web APIs

[sorpippo]

Hi folks.

I've installed Pear SOAP on my machine in order to have Google at my fingertips.
When I run the script I can't see any result (the query is ok). my script is

include("SOAP/Client.php");

    $client = new SOAP_Client('http://api.google.com/search/beta2');


 $arguments = array(
         'key' => 'my key',   
         'q'   => $query,                          'start' => 1, 
         'maxResults' => 10,
         'filter' => true, 
         'restrict' => '', 
         'safeSearch' => true,
         'lr' => '',
         'ie' => '',
         'oe' => '' 
    );

$result = $client->call("doGoogleSearch", $arguments,"urn:GoogleSearch", "urn:GoogleSearch");

foreach ($results['resultElements'] as $r){
echo "<li><a href=" . $r['URL'] . ">" .$r['title'] . "</a>";
echo "<br>";
echo $r['snippet'] . "(" . $r['cachedSize'] . ")";
echo "<p>";
}

Does anyone have successfully perfomed this work?

Ciao.

Giuseppe.
