PHP5 SOAP: Debugging

SoapClent allows us to debug messages sent and received. This is done by setting the trace option to 1 when instantiating SOAP. This gives us the SOAP headers and envelope body.

$client = new SoapClient('http://api.google.com/GoogleSearch.wsdl',array('trace' => 1));
$results = $client->doGoogleSearch(NULL, $query, 0, 10, FALSE, '',FALSE, '', '', '');
echo $client->__getLastRequestHeaders();
echo $client->__getLastRequest();

This will output the header requests of the file, followed by the envelope bodies.
