This is the Title of the Book, eMatter Edition

Chapter 1: Introduction to Flash Remoting

Switch back to the Flash movie and change the myURL variable in Example 1-1 to

point to the .NET version of the Flash Remoting gateway, such as:

var myURL = "http://yourservername/flashremoting/gateway.aspx";

This is the only change that has to be made to the Flash movie. It is necessary

because the .NET version of the Flash Remoting gateway is implemented differently

than the Java and ColdFusion MX versions.

Save the Flash movie and test it. You should see the output from the DLL (“Hello

World from ASP.NET DLL”) in Flash’s Output window.

PHP

The Hello World application (and other applications) must be set up a bit differ-

ently in PHP than in other environments. Flash Remoting with PHP is class-based,

due to requirements of the AMFPHP library. That is to say, all Flash Remoting ser-

vices must be written as classes in PHP. To install the AMFPHP library, simply

download the source release package and copy its flashservices directory to your web

server’s document root (see Chapter 9 for additional details). Because the class is

named com.oreilly.frdg.HelloWorld, AMFPHP searches in the services path for a

HelloWorld.php file. The main flashservices directory resides under the web root,

with the AMFPHP classes in that directory. The services directory resides in this

flashservices directory as well.

When building PHP remote services, you should include a gateway.php file in your

server-side application in the directory for your current project. This creates the

Flash Remoting gateway and includes the necessary files. The gateway.php file

(shown in Example 1-6) for the Hello World example should be saved in the

webroot\

com\oreilly\frdg directory.

Create a file named HelloWorld.php and place it into the following directory, where

webroot is the root of your web server and com\oreilly\frdg\ matches the service path

specified by the initial portion of the

myServicePath variable in Example 1-1:

webroot\flashservices\services\com\oreilly\frdg

Add the code shown in Example 1-7 to your HelloWorld.php page.

Example 1-6. PHP Remoting gateway.php file contents

<?php

/* File: gateway.php

Instantiates the Gateway for the HelloWorld Application */

require_once '/app/Gateway.php'; /* Require files */

$gateway = new Gateway( ); /* Create the gateway */

$gateway->setBaseClassPath('/services/com/oreilly/frdg');

/* Set the path to where the service lives */

$gateway->service( ); /* Start the service */
