PHP and Rich Internet Applications
0 likes2,791 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.

- 8. RIA Characteristics • Full applications • Could replace desktop apps • Applications, not web pages
- 11. What’s in it for me? for my employer?
- 12. Rich Internet Applications “ are the next evolution of the web. ” Source: Gartner Research, May 11, 2005
- 13. Builds on existing skills and knowledge
- 14. $
- 15. Saved ~160 GB in 3 hrs
- 16. User experience matters
- 17. Client Options • Ajax (In Browser) • Java (Sun) • XUL (Mozilla) • XAML (Microsoft) • MXML (Adobe Flex)
- 18. Ajax Examples
- 19. XUL Examples
- 20. XUL Examples Songbird
- 21. XAML Examples
- 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>”; ?>
- 31. PHP and RIAs • Transfer PHP objects to the client directly • JSON - JavaScript Object Notation • AMF - ActionScript Messaging Format
- 32. JSON and PHP
- 37. Flex with AMFPHP <?php //connect to the database mysql_connect ... //get the data $ResultObject = mysql_query( “SELECT * from recipes”); ... return( mysql_fetch_object( $ResultObject ) ); ?>

- 40. 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
- 41. What’s next?
- 42. 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
- 44. Apollo enables... • Offline / 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
- 47. THANK YOU!
