ارسال اطلاعات از اندروید به پایگاه دادهmysql(فوری)

سلام

من میخام از اندروید یه سری اطلاعات بگیرم و در پایگاه داده sqlاون ها رو ذخیره کنم. اما  این داد ه ها  در پایگاه داده ذخیره نمیشه. ممنون میشم اگه راهنمایی کنید.قبلا دریافت اطلاعات از پایگاه داده و نمایش در اندروید رو انجام دادم و نتیجه درستی گرفتم و اتصالات برقرار هست.

دو اکتیویتی دارم اکتیویتی اول برای یه سری اتصالات و ..هست و اکتیویتی دوم  برای دریافت اطلاعات از کاربر 

 index.php:



 <?php

 if (isset($_REQUEST['action'])){
 $action = $_REQUEST['action'];
 }else{
 echo "Error";
 exit();

 }

 if ($action=="read"){
 read();
 }else if ($action == "insert"){
 insert();
 }



 function connection(){
 $con = mysqli_connect("localhost","root","","teldb");
 if (mysqli_connect_errno()) {
 echo "Failed to connect to MySQL: " . mysqli_connect_error();
 }
 mysqli_set_charset($con,"UTF8");
 return $con;
 }

 function read(){
 $con = connection();
 $result = mysqli_query($con,"select * from teldata");
 $output = array();
 $fetch_data = array();
 
 while ($row = mysqli_fetch_array($result)){
 $fetch_data['person_id'] = $row['person_id'];
 $fetch_data['person_name'] = $row['person_name'];
 $fetch_data['person_family'] = $row['person_family'];
 $fetch_data['person_tel'] =$row['person_tel'];
 $fetch_data['address'] = $row['address'];
 $output[] = $fetch_data;
 }

 echo json_encode($output);
 mysqli_close($con);

 }


 function insert(){

 $name = $_REQUEST['person_name'];
 $family = $_REQUEST['person_family'];
 $tel = $_REQUEST['person_tel'];
 $address = $_REQUEST['address'];


 if (!empty($name) && !empty($family) && !empty($tel) && !empty($address)){
 $con = connection();
 $result = mysqli_query($con,"insert into teldata values (0,'$name','$family','$tel','$address')");
 mysqli_close ($con) ;

 }
