Question

hey i am making an android app where user's request in the format of json . Their request will look like this..

  <?php
require "init1.php";



$jsonObject = $_GET["UserDetails"];
$obj = json_decode($jsonObject);
$email = $obj->Email;
 $password = $obj->Password;
.......


echo $email; //Everthing i fetch from jsonObject is null. Why?


?>

ThankYou, is it correct how i am fetching in php??

In test.php you can catch the data with $_GET['UserDetails'] then decode it with json_decode($_GET['UserDetails')

Then you can iterate it with a foreach loop

Example:

if(isset($_GET['UserDetails'])) {
     $details = json_decode($_GET['UserDetails']);

      foreach($details as $key => $val) {
           echo $key.' = '.$val;
      }
