web_serviceにデータを投稿中

Question

このリンクを使用してweb_serviceにデータを送信しようとしています。

http://localhost/FixItApp/admin.php?serial_number=mmm&items=asd&brand=qwe&price=sd&user_name=vfd

が、データが掲載されていない、なぜfigure_outすることはできません。 ここは私のweb_serviceです。

<?php 

$myfile = fopen("newfile.txt", "w") or die("Unable to open file!"); 
$txt = "not set"; 
if(isset($_REQUEST)) 
    { 
     $txt = serialize($_REQUEST); 
    } 

fwrite($myfile, $txt); 
fclose($myfile); 

require_once "DatabaseConnection.php"; 
$result = null; 

if ($_GET) 
    { 
     /* User table attribute */ 
     $serial = filter_input(INPUT_GET, "serial_number", FILTER_SANITIZE_STRING); 
     $item = filter_input(INPUT_GET, "items", FILTER_SANITIZE_STRING); 
     $item_brand = filter_input(INPUT_GET, "brand", FILTER_SANITIZE_STRING); 
     $item_price = filter_input(INPUT_GET, "price", FILTER_SANITIZE_STRING); 
     $name = filter_input(INPUT_GET, "user_name", FILTER_SANITIZE_STRING); 


     if(is_null($serial)) 
      { 
       echo "Null Values"; 
      } 
     else 
      { 
       $select_ExistUser = @"SELECT serial_number from admin WHERE serial_number = '$serial'"; 
       $resultUser = selectQuery($select_ExistUser); 
       if(count($resultUser)==0) 
        { 
         $query_one = "INSERT INTO admin(serial_number, items, brand, price, user_name) 
              VALUES('$serial', '$item', '$item_brand', $item_price, '$name')"; 

         $result = insertQuery($query_one); 

         $insert_id = $db->insert_id; 

         if($insert_id) 
          { 
           echo "Great"; 
          } 
        } 
       else 
        { 
         echo "ResultUser > 0"; 
        } 

      } 
    } 
if ($result) 
    { 
     $arr= [ 
       "result" => $insert_id, 
       "status_message" => "Good", 
       "status_code" => 1 
       ]; 
    } 
else 
    { 
     $arr = [ 
       "result" => $result, 
       "status_message" => "Sorry!", 
       "status_code" => -1 
       ]; 
    } 
echo json_encode($arr);
