I’ve updated my “parameterdemo” to include a couple PHP pages. The latest trunk (0.8.1-dev) now supports PHP through the use of Quercus. To enable it simply set a context parameter in your web.xml and include the quercus and resin-utils jars in your WEB-INF/lib. See the zip file for a complete example (eclipse + ant).

Once you deploy the war, go to these urls to test (update your port to match your servers setting):

PHP example getting value from Red5 application: 

<a href="http://localhost/parameterdemo/getparam.php">http://localhost/parameterdemo/getparam.php</a>

Same example with debug output: 

<a href="http://localhost/parameterdemo/getparam.php?debug=true">http://localhost/parameterdemo/getparam.php?debug=true</a>

Java servlet example: 

<a href="http://localhost/parameterdemo/myservlet">http://localhost/parameterdemo/myservlet</a>

The web.xml entry must look like so:

	<context-param>
	   <param-name>enable-php</param-name>
	   <param-value>true</param-value>
	</context-param>

Note: You dont have to install Resin to use Quercus, simply download one of the wars on this page: http://quercus.caucho.com/ and grab the libraries from WEB-INF/lib

I recall seeing a question from a user about accessing servlet parameters from their Red5 application, so I have created a small demo which shows how to not only access sevlet parameters from Red5 apps but the other way around as well.

Retrieve a servlet context parameter from inside a Red5 application (AppContext -> Servlet)

1. Grab a reference to the application context

ApplicationContext appCtx = getContext().getApplicationContext();

2. Get the servlet context

ServletContext ctx = ((XmlWebApplicationContext) appCtx).getServletContext();

3. Get the context parameter

String param = ctx.getInitParameter("myparam");

Retrieve an application context parameter from a inside a servlet (Servlet -> AppContext)

1. Get the servlet context

ServletContext ctx = getServletContext();

2. Grab a reference to the application context

ApplicationContext appCtx = ctx.getAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE);

3. Get the bean holding the parameter

MyBean bean = appCtx.getBean("mybean");
String param = bean.getParameter("myparam");

Sample project files: parameterdemo.zip

Instructions:

Unzip the demo and create a new directory named parameterdemo in your red5/webapps directory, then restart your server.

Open your browser and go here: http://localhost/parameterdemo/myservlet?paramName=myparam

You should see “Hello World”

To test the Red5 application you will need to create a Flex or Flash application that connects to: rtmp://localhost/parameterdemo

Then simply call “getParameter” passing a parameter name you want the value of. The name must match a context param in the web.xml file.
