Again, accessing those webservices through .NET is pretty easy with its built in function. But, to access it through languages like PHP, requires some analysis, particularly for those who are doing it for first time.
The nusoap.php is a populat choice to access the webservice via Php.

It can be downloaded from the following sourceforge URL.

$client->setcredentials($username,$password);

$err = $client->getError();

if ($err) {

echo '

' . $err . '

';

}

// Doc/lit parameters get wrapped

$param = array('strKeyWord' => 'java','pageLength'=>(int)'5');

$result = $client->call('SimpleSearch', $param, '', 'http://tempuri.org/SimpleSearch', false, true);

// Check for a fault
