error_reporting(0); include("db_config.php"); $response = array(); if (isset($_get['id'])) {     $id = $_get['id'];     $item = $_get['item'];      $r = mysql_query("select department_id student st_id = '$id'");     $row = mysql_fetch_array($r);     $department_id = $row[0];     $r = mysql_query("select subject_name subject subject_code ='$item'");     $row = mysql_fetch_array($r);     $subject_name = $row[0];     $result = mysql_query("insert `sis_fyp`.`student-subject` (`st_id`, `subject_code`, `status`, `grade`, `department_id`, `subject_name`) values ('$id', '$item', 'repeat', 'w', '$department_id', '$subject_name');");      if ($result>0) {         $response["success"] = 1;     } else {         $response["success"] = 0;     }     // echoing json response     echo json_encode($response); }

just make php script above , pass url in , android like:

wwww.yoururl.com?id=$id&item=$item
