Easy creation of WSDL documents

Create a simple WSDL document from the documented PHP classes.

Assumptions

• Expose only public methods
• Adding a whole class
• Class must be documented

Example PHP class

/**
 * Sample class of service
 */
class Sample_Service {

    /**
     * Test service function
     *
     * @param string $first  First string
     * @param int    $second Second is number
     * @param array  $third  Third is an array
     * @return string This result description
     */
    public function test_method($first, $second, $third) {

    }
}

Example usage

// create new parser
$wsdl = new Wsdl_Document();

// set service name
$wsdl->set_name('MyService');

// add an array of classes
$wsdl->add_class(array(
    'Sample_Service' => 'http://example.com/server',
));

$wsdl->save('document.wsdl'); // Result: bool

$wsdl->get_document();        // Result: string - WSDL document

$wsdl->validate();            // Result: bool

The resulting WSDL document
