PHP and Rich Internet Applications
0 likes2,788 views
This document discusses PHP and Rich Internet Applications (RIAs). It notes that RIAs can replace desktop applications and are the next evolution of the web. PHP can be used to build RIAs by reading in XML from a PHP backend using REST, transferring PHP objects directly to the client using JSON or AMF, or making PHP apps that serve as services for any front end like Ajax, XAML, or Flex. It also briefly mentions tools for developing Flex applications from PHP like Adobe's web compiler for Flex apps.

- 26. 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?
- 27. PHP and RIAs • Read in XML from a PHP backend (REST)
- 28. REST with PHP <?php //connect to the database mysql_connect ... //get the data mysql_query( “SELECT * from recipes”); ... //transform into XML print “<recipes><recipe id=’1’ name=’cake’/><recipe id=’2’ name=’hotdog’/></recipes>”; ?>
