Chapter 8. Demo Application > The Server Side
8.1. The Server Side
Our GWT application connects to a PHP file running on the Apache web server. This PHP file provides the information from the server, which ends up displayed in the text fields. Here's the source code for the PHP:
<?php
//set the content-type HTTP header
header("Content-Type: text/plain; charset=UTF-8");
//Indicate that the browser should not cache the received value
header("Cache-Control: no-cache");
$info_array = array(
"server" => $_SERVER["SERVER_SOFTWARE"],
"date" => date("l, F j, Y H:i:s",$_SERVER["REQUEST_TIME"]),
"browser" => $_SERVER["HTTP_USER_AGENT"]);
echo json_encode($info_array);
?>
