arduino+XAMPP+mysql+php data sending to web server

Hi,ı want to push data a mssql server using arduino and php codes.So firstly i tried send data a mysql server with xampp.My codes and php files given below;
/*
Web client

This sketch connects to a website (http://www.google.com)
using an Arduino Wiznet Ethernet shield.

Circuit:

  • Ethernet shield attached to pins 10, 11, 12, 13

This codes sending data my server in every 32 sec.But arduino serial monitor gives some error about php codes.

ıf you share your thoughts ı wil be glad.also ı attach my server web page data pic.

This codes sending data my server in every 32 sec

The Arduino code is not. The Arduino code makes ONE call to the server, in setup(). It never calls the server again.

$Leddurum=$_GET["Leddurum"];

The GET request does NOT include any variables. So, this statement is looking for the value of a variable that is NOT part of the GET collection.
