How to use RESTfulWebServiceClient for php server in CN1 - codenameone

Question

I want to generate the code for the server in php and use it as the backend instead of webservices in java. I noticed that, webservices Wizard in CN1 generated details on the server side. In my own case I want to create the server in php and use RESTfulWebServiceClient to point to the url.
Pls how do I go about this?
Is there any webservice Wizard that can generate the php server like java in netbeans?
In the auto re-new subscription in in-app purchase can I interact with the mysql database without using RESTfulWebServiceClient?
Thanks for your response
I have created the webservices in php and used the url in codename one. I was able to use the url to submit receipt into the database. see the image below
I still have challenges, the error code below was generated

After subscribing and I press Syns Receipts. Subscribe to remove ads is still there. Pls help Thanks
This is my php webserver code.
<?php
use \Psr\Http\Message\ServerRequestInterface as Request;

echo "customers";
// Get All customers
$sql = "SELECT * FROM receipts";
try{
$db = new db();
$db = $db->connect();
$stmt = $db->query($sql);
$customers = $stmt->fetchAll(PDO::FETCH_OBJ);
$db = null;
echo json_encode($customers);
}catch(PDOException $e){
echo '{"error": {"text": '.$e->getMessage().'}';
}
});

This is my url and part of my code in codename name:
private static final String receiptsEndpoint = "http://slimapp/api/customers";
private static final String receiptsEndpoint2 = "http://slimapp/api/customer/add";
private ReceiptStore createReceiptStore() {
return new ReceiptStore() {
RESTfulWebServiceClient client = createRESTClient(receiptsEndpoint);

// req.setPost(true);
// req.setHttpMethod("post"); //Change to GET if necessary
req.setUrl(receiptsEndpoint);
}

for (Map m : rowset) {
Result res = Result.fromContent(m);
Receipt r = new Receipt();
r.setTransactionId(res.getAsString("transactionId"));

};
}
pls help to review my code in above what I am missing maybe in php webserver code or in codename one code. I was able to subscribe and receive the message that the subscription was succesfull and the records was inserted into the database, when I click on Syns Receipts Button, No receipt was updated and the record goes to the database. Pls help, I dont know what is going wrong

Our webservice wizard expects a Java server and doesn't generate PHP code.
You can use any restful service from Codename One by using ConnectionRequest and invoking a URL with GET, POST, PUT & DELETE.
See the developer guide section on networking. If you create a webservice in PHP and have the curl usage I can help with the Codename One equivalent.
