//and receiving @ server like

$username =$_post["user_name"];

use getparams() method in request send parameter server
can set string body after url:

  jsonarrayrequest request = new jsonarrayrequest(request.method.post, "url", "you can send string here body", new response.listener<jsonarray>() {         @override         public void onresponse(jsonarray response) {             // parse json array          }     }, new response.errorlistener() {         @override         public void onerrorresponse(volleyerror error) {             // handle errors here         }     }) {         @override         protected map<string, string> getparams() {   // send parameters here             map<string, string> params = new hashmap<>();             params.put("key1", "value1");             // add other parameters             return params;         }     };     mysingleton.getinstance(this).addtorequestqueue(request);
