How I can generate the WSDL automatic from a php file?
for a file like this:
<?php

require_once('nusoap.php');
$s = new soap_server;
$s->register('hello');
function hello($name){
// optionally catch an error and return a fault
if($name == ''){
return new soap_fault('Client','','Must supply a valid name.');
}
return "hello $name!";
}
$s->service($HTTP_RAW_POST_DATA);

?>

Thanks

You don't need to generate WSDL. It's done by nusoap. You only have to register your function(s) and their parameters. Then when you invoke your script via WEB and WSDL argument is set, you get WSDL file. If you invoke without WSDL, you get description and link to WSDL file.
