Giving the code below:

Myservice class after adding substract,multiply and divide

class MyService { public function add($x, $y) { return $x + $y; } public function subtract($x, $y) { return $x - $y; } public function multiply($x, $y) { return $x * $y; } public function divide($x, $y) { return $x/$y; } }

$options = array( 'uri' => 'http://server/namespace', 'location' => 'http://swe.umbc.edu/~pcomitz/programs/wk4/soapserver.php', );

$server = new SoapServer(null, $options); $server->setObject(new MyService()); $server->handle();

Create a php form with radio buttons for add, subtract, multiply, and divide. You should also have inputs for two numbers. Your should invoke the appropriate method based on the radio button that is selected (you do not need to validate the input) .
