Question

I have a several problems to moment to create a WSDL with REST in PHP. I read a little bit about this, supposedly REST use WADL. I need a library or framework that generated a WADL or type WSDL of my code PHP (class, methods, vars).
Thanks a lot!
I created a simulation with php but this no get the return vars

... Methods
... Vars
if(isset($_GET['wadl'])):
header('Content-Type: text/xml');
$foo = new proveedores();
$get_class = get_class($foo);
// create the new XML document
$dom = new DOMDocument('1.0', 'iso-8859-1');
// create the root element
$list_of_teams = $dom->createElement($get_class);
$dom->appendChild($list_of_teams);
$class = new ReflectionClass($get_class);
$methods = $class->getMethods();
foreach ($methods as $m) {
$method = $class->getMethod($m->name);
// create the first element
$team = $dom->createElement($m->name);
$list_of_teams->appendChild($team);
$parameters = $method -> getParameters();
if(!empty($parameters)):
foreach ($parameters as $p) {
$name = $team->appendChild($dom->createElement('parameters'));
$name->appendChild($dom->createTextNode($p -> name));
}
endif;
}
print $xml_result = $dom->saveXML();
endif;
