Google APIs with PHP

Hi all, I am new to PHP and just tested out using NuSoap to query Google database. The code is written by Harish Kamath. However, it doesn't work without error message. The web server I used support PHP. Also I downloaded the required nusoap.php class file and put it in the same directory with nusearch.php, which query Goodgle database and I have Google's licence key for its APIs. The code is as following: <html> <head><basefont face="Arial"></head> <body> <? if (!$_POST['q']) { ?> <h2>Search</h2> <form action="<?=$_SERVER['PHP_SELF']?>" method="post"> Search term: <input type="text" name="q"> </form> <? } else { // include the class include("nusoap.php"); // create a instance of the SOAP client object $soapclient = new soapclient("http://api.google.com/search/beta2"); // uncomment the next line to see debug messages // $soapclient->debug_flag = 1; print("Before params"); // testing // set up an array containing input parameters to be // passed to the remote procedure $params = array(

     'key' => 'LHZMFvNQFHJ/jGT0d6N8Iu83QVsz49rr',   // Google license key
     'q'   => $_POST['q'],         // search term
     'start' => 0,                 // start from result n
     'maxResults' => 10,           // show a total of n results
     'filter' => true,             // remove similar results
     'restrict' => '',             // restrict by topic
     'safeSearch' => true,         // remove adult links
     'lr' => '',                   // restrict by language
     'ie' => '',                   // input encoding
     'oe' => ''                    // output encoding

); print("before invoke the doGoogleSearch method"); // invoke the method on the server $result = $soapclient->call("doGoogleSearch", $params,"urn:GoogleSearch", "urn:GoogleSearch"); print("before printing results"); // print the results of the search if ($result['faultstring']) { ?> <h2>Error</h2> <? echo $result['faultstring'];?> <? } else { ?> <h2>Search Results</h2> Your search for <b><?=$result['searchQuery']?></b> produced <?=$result['estimatedTotalResultsCount']?> hits. <br> <ul> <? print("before displaying result"); if (is_array($result['resultElements'])) { foreach ($result['resultElements'] as $r) { echo "<li><a href=" . $r['URL'] . ">" . $r['title'] . "</a>"; echo "<br>"; echo $r['snippet'] . "(" . $r['cachedSize'] . ")"; echo "<p>"; } } ?> </ul> <? } } ?> </body> </html> Would be very much appreciated if someone can help me out.
