body: <p>Here is my code of Qt creator to send the data to PHP server and get the response.</p>
  
  <pre><code>QNetworkAccessManager *manager = new QNetworkAccessManager(this);
  QNetworkAccessManager::connect(manager, SIGNAL(finished(QNetworkReply*)),this ,          SLOT(replyFinished(QNetworkReply*)));
  QNetworkRequest *request = new   QNetworkRequest(QUrl("http://68.169.55.41/fss/verifylogindetails.php"));
  QByteArray postData =" {\"estate_id\":\"hsr\",\"emp_pin\":1234,\"emp_id\":\"santhosh\"}";
  request-&gt;setRawHeader( "User-Agent" , "Mozilla Firefox" );
  request-&gt;setRawHeader( "charset", "utf-8" );
  request-&gt;setRawHeader( "Connection", "keep-alive" );
  manager-&gt;post(*request, postData );
  }
  
  void MainWindow::replyFinished(QNetworkReply *reply)
  {
   QString data = reply-&gt;readAll().trimmed();

  die('Could not connect: '.mysql_error());
  }
  mysql_select_db($db_name, $con);
  $result = mysql_query("SELECT * FROM login_data_table");
  while($row = mysql_fetch_array($result))
  {
  if((strcasecmp( $row['Emp_Id'], $data-&gt;emp_id) == 0) &amp;&amp; ($row['Emp_Pin'] == $data- &gt;emp_pin) &amp;&amp; (strcasecmp( $row['Estate_Id'], $data-&gt;estate_id) == 0))
