I get error while I send three array post with Alamofire in database?

Question

This is my php code. I need to send here 3 parameters like cammand , mobile and token. include "../db.php";

//$_POST['command'] ;//
$command = $_POST['command'];
if ($command == "register_user") {//register user
    $mobile = $_POST['mobile'];
    $token = $_POST['token'];
    $sql = "SELECT * FROM  tbl_user where mobile ={$mobile}";
    $result = mysqli_query($connection, $sql);
    $num = mysqli_num_rows($result);

This my swift code.

import Foundation
import UIKit
import Alamofire
class LoginViewController: UIViewController {
    
     let appDelegate = UIApplication.shared.delegate as! AppDelegate
     
    @IBOutlet weak var inputTelephoneNumber: UITextField!
    
    override func viewDidLoad() {
        super.viewDidLoad()
       
    }
    
    @IBAction func loginBtn(_ sender: Any) {
        
        let Parametrs : Parameters = [
            
            "command": "register_user",
            "mobile": inputTelephoneNumber.text!,
            "token": appDelegate.myToken!
            
        ]
        AF.request("http://192.xxxxxxxxx/xxxxxxxx/api/sms_verify.php", method: .post, parameters: Parametrs, encoding: JSONEncoding.default)
        .responseJSON { response in
            print(response)
    } 
        
       let tokenURL = "http://192xxxxxx/xxxxxxxxx/api/sms_verify.php"
       if let url = URL(string: tokenURL) {
           let task = URLSession.shared.dataTask(with: url) {
               data, response, error in
               if error != nil {
                   print(error!)
               } else {
                   if let responseString = String(data: data!, encoding: .utf8) {
                       print(responseString)
                   }
               }
           }
           task.resume()
       }
   
    }
    
    
   


}

I get this error from xcode.

<br />
<b>Notice</b>:  Undefined index: command in <b>/opt/lampp/htdocs/foroshgah1/api/sms_verify.php</b> on line <b>5</b><br />

failure(Alamofire.AFError.responseSerializationFailed(reason: Alamofire.AFError.ResponseSerializationFailureReason.jsonSerializationFailed(error: Error Domain=NSCocoaErrorDomain Code=3840 "Invalid value around character 0." UserInfo={NSDebugDescription=Invalid value around character 0.})))

I try to send three parameters like cammand = register_user , mobile and token.
I try to send them like json encode but I did not know I correct form or no?

My Php code work fine without any problem. I have problem in swift — Alireza, Sep 29 '20 at 07:50
If you are sending your data as JSON, then you need to modify your PHP code - PHP _does not_ populate $_POST, when you send JSON. Or you need to send something else from the client side in the first place - like a “normal” `application/x-www-form-urlencoded` request. — 04FS, Sep 29 '20 at 07:56
I say that my Php code work fine and my android app work with this Php very fine. — Alireza, Sep 29 '20 at 07:59
You aren't sending an array, you are sending a dictionary. You have at the same time a URLSession code and a Alamofire one, it's unclear. If you code works well with Android, might want to share the code? Does it work with a `cURL` command too? POSTMAN? — Larme, Sep 29 '20 at 08:13
@Alireza just change the `encoding` that you send to request function from `JSONEncoding.default` to `URLEncoding.default`. — gcharita, Sep 29 '20 at 08:32
@gcharita, please post your comment as an answer. Alireza please accept the answer that gcarita posts. — jnovack, Sep 29 '20 at 10:37

To pass URL encoded parameters in a post request, you need to call the request function of Alamofire passing an instance of URLEncoding as encoding parameter:

AF.request(
    "http://192.xxxxxxxxx/xxxxxxxx/api/sms_verify.php",
    method: .post,
    parameters: Parametrs,
    encoding: URLEncoding.default
).responseJSON { response in
    print(response)
}
