[SOAP] PHP 4.2.02 using SOAP

Hi, i'm confussed because i have been testing a client soap using a webservice built in Delphi. That works OK, but when i tried to use, for example the Google Search webservice, i receive nothing in the result array. The other problem is that i can't see the fault code due to the PHP version. Could be the recomendation upgrading PHP? Here there is the code // ------------------------ $parametros = array('key' => 'SmjRaZtQFHLSvBlTlYOsJZV0bIB2uPmS', 'q' => $_GET['q'], 'start' => 0, 'maxResults' => 15, 'filter' => false, 'restrict' => '', 'safeSearch' => false, 'lr' => '', 'ie' => 'latin', 'oe' => 'latin' ); require ('nusoap.php'); $s = new soapclient('http://api.google.com/GoogleSearch.wsdl', 'wsdl'); $results = $s->call('doGoogleSearch',$parametros,'urn:GoogleSearch','urn:GoogleSearch') ; if ( is_array($results['resultElements']) ) { print "<p>Resultados para '" . $_GET['q'] . "'. Encontrados " . $results['estimatedTotalResultsCount'] . " resultados, los 10 primeros son:</p>"; foreach ( $results['resultElements'] as $result ) { print "<p><a href='" . $result['URL'] . "'>" . ( $result['title'] ? $result['title'] : 'sin t&iacute;tulo' ) . "</a><br />" . $result['URL'] . "<br />" . ( $result['snippet'] ? $result['snippet'] : 'sin recorte' ) . "</p>"; } } else print 'No hay resultados....<br><br>'; // ------------------------ Thanks beforehand Jr/
