title: Sending data to php page with java
body: <p>I am trying to send the POST data from java to a PHP page. However it is not working. Whatever I echo in the php page works fine but when I send data it gives- 'undefined index'
  What could be the problem ?
  This is my java file.</p>
  
  <pre><code>import java.net.*;
  import java.io.*;
  
  class Main {
  public static void main(String args[]) throws IOException {
  
      URL url = new URL("http://localhost/CD/user/test");
      String result = "";
      String data = "fName=" + URLEncoder.encode("Atli", "UTF-8");
      HttpURLConnection connection = (HttpURLConnection) url.openConnection();
      try {
  
          connection.setDoInput(true);
          connection.setDoOutput(true);
          connection.setUseCaches(false);
          connection.setRequestMethod("POST");
          connection.setRequestProperty("Content-Type",
                  "application/x-www-form-urlencoded");
  
          // Send the POST data
          DataOutputStream dataOut = new DataOutputStream(
                  connection.getOutputStream());
          dataOut.writeBytes(data);
          dataOut.flush();
          dataOut.close();
  
          BufferedReader in = new BufferedReader(new InputStreamReader(
                  url.openStream()));
  
          String g;
          while ((g = in.readLine()) != null) {
              result += g;
          }
          in.close();
  
      } finally {
          connection.disconnect();
          System.out.println(result);
      }
  
  }
  }
  </code></pre>
  
  <p>And here is my php controller:</p>
  
  <pre><code>public function test(){
  
      $test=$_POST['fName'];
      $all="This is a ";
      $all=$all." ".$test;
      echo $all;
  
  
  
  }  
  </code></pre>
  
  <p>When I just send a url request , I get the ouput as 'This is a'. So it is connecting to the url and everything but while sending data, it is not working. Please help! Thank you.</p>
