//
// this is an updated version of the PHP script from the flashKit.com example
// file submitted by Joseph Miller. (How_to_M-Joseph_M-702.zip)
// this one works with PHP 4.3.0
//
// How to make Flash listen to PHP
// get the archive How_to_M-Joseph_M-702.zip for the rest of this example.
// you will find it at
// http://www.flashkit.com/tutorials/Backend/How_to_M-Joseph_M-702/How_to_M-Joseph_M-702.zip
//
// now for the updates ...
//
// there is no need for the html, header and body tags in
// the newer, more error tolerant browsers.
//
// besides, html tags will just be a problem for flash actionscript
//
// get the request method so that we can manually test this thing
// in a browser window using the GET method.
$method = $_SERVER['REQUEST_METHOD'] ;
//
// there are two ways to send data to PHP, the GET and the POST methods
// if you manually type a URL in a browser window you will use "GET".
// (see the GET example at the end of this file ... )
//
// the POST method is used with forms and when our flash actionscript
// uses "POST".
if ( strcmp($method,"POST") == 0) {
$page = $_POST['page'];
$who = $_POST['who'];
$what = $_POST['what'];
$where = $_POST['where'];
$web = $_POST['web'];
} elseif ( strcmp($method,"GET") == 0) {
$page = $_GET['page'];
$who = $_GET['who'];
$what = $_GET['what'];
$where = $_GET['where'];
$web = $_GET['web'];
}
//
// i like to use sprintf, because I am more familiar with it
$result = sprintf("%s works as a %s in %s and may be found on the web at %s.",
$who,$what,$where,$web);
//
// these two lines are all that flash actionscript will see,
// and all that it cares about.
// the method is not important, the format is. use echo, print, printf,
// or any other method that you understand.
echo "&result=".$result;
print "&loading=NO";
//
// external PHP variable access using PHP version 4.3
// (first introduced in PHP 4.1.0)
// (use HTTP_POST_VARS and HTTP_GET_VARS for previous PHP versions)
//
// for POST variables use
// $who = $_POST['who'];
// $who = $HTTP_POST_VARS['who'];
//
// for GET variables use
// $who = $_GET['who'];
// $who = $HTTP_GET_VARS['who'];
//
// more on the GET format
//
// below is a test string for manually testing the script.
// the order of the variables is not important as long as they are supplied.
//
// http://www.myserver.com/ScriptA.php?who=me&what=that%20stuff&where=there&web=the%20web%20address
//
// remember to use URL syntax and character replacements, e.g. a space is %20
