title: Send JSON from Java to PHP through Post
body: <p>I am doing an Android program that is supposed to send data from the tablet to a PHP Web Service. The code for sending the JSON:</p>
  
  <pre><code>package com.example.shvalidation;

          new TestThread().execute();
      }
  
      @Override
      public boolean onCreateOptionsMenu(Menu menu) {
          // Inflate the menu; this adds items to the action bar if it is present.
          getMenuInflater().inflate(R.menu.main_menu_layout, menu);

              } catch (IOException e) {
                  e.printStackTrace();
              } finally {

  <p>The PHP Web Service:</p>
  
  <pre><code>&lt;?php
      ob_start();
  
      var_dump(json_decode(file_get_contents('php://input')));
  
      $out = ob_get_contents();
  
      ob_end_clean();
  
      $f = fopen('out.txt', 'w+');
  
      fwrite($f, html_entity_decode($out));
  
      fclose($f);
  ?&gt;
  </code></pre>
  
  <p>I have tried different methods for getting the JSON, but none of them have worked for me. Maybe the fine people of StackOverflow can help me out with this, as they always have for every other problem that I've had. </p>
