RIA Characteristics
• Full applications
• Could replace desktop apps
• Applications, not web pages
What’s in it
for me?for my employer?
Rich Internet Applications are the next evolution of the web.

User experience matters
Client Options
• Ajax (In Browser)
• Java (Sun)
• XUL (Mozilla)
• XAML (Microsoft)
• MXML (Adobe Flex)
Ajax Examples

To Think About
• Reach - How many people will view this application? What platform will they be on? Is it an open or closed platform?
• Rich - Can I integrate rich content easily, like video, audio and animations?
• Tools - What will I use to build this application? How will I debug?
PHP and RIAs
• Read in XML from a PHP backend (REST)
REST with PHP<?php
//connect to the databasemysql_connect ...
//get the datamysql_query( “SELECT * from recipes”);...
//transform into XML
print “<recipes><recipe id=’1’ name=’cake’/><recipe id=’2’ name=’hotdog’/></recipes>”;
?>
PHP and RIAs
• Transfer PHP objects to the client directly
• JSON - JavaScript Object Notation
• AMF - ActionScript Messaging Format
JSON and PHP
Flex with AMFPHP
<?php
//connect to the databasemysql_connect ...
//get the data$ResultObject = mysql_query( “SELECT * from recipes”);...
return( mysql_fetch_object( $ResultObject ) );
?>

Recap
• Build PHP apps as services that can be used by any front end - Ajax, XAML, Flex etc...
• Rich clients and components allow you to simplify your PHP code
What’s next?
Web Compiler for Flex Applications
• http://labs.adobe.com
• Allows you to create MXML, ActionScript, upload to the server and compile there, similar to developing PHP applications
• O!ine / Occasionally Connected
• Applications can run in background
• Network
• HTTP
• XML-RPC / SOAP / Rest based web services
• Binary and XML sockets
• File I/O
• Local storage / Settings API
• Custom Chrome
• Shape
• Alpha
Apollo enables...
