PHP and Rich Internet Applications Presentation Transcript

  • 1. PHP and Rich Internet Applications Mike Potter http://www.riapedia.com/ mike.potter@adobe.com
  • 2. Fast Easy
  • 3. <?php if (!$link = mysql_connect('mysql_host', 'mysql_user', 'mysql_password')) { !! echo 'Could not connect to mysql'; !! exit; } if (!mysql_select_db('mysql_dbname', $link)) { !! echo 'Could not select database'; !! exit; } $sql! ! = 'SELECT foo FROM bar WHERE id = 42'; $result = mysql_query($sql, $link); if (!$result) { !! echo quot;DB Error, could not query the databasenquot;; !! echo 'MySQL Error: ' . mysql_error(); !! exit; } mysql_free_result($result); return($result); ?>
  • 4. function PMA_getSearchSqls($table, $search_str, $search_option) { global $err_url, $charset_connection; // Statement types $sqlstr_select = 'SELECT'; $sqlstr_delete = 'DELETE'; // Fields to select $res = PMA_DBI_query('SHOW ' .

  • 5. www.riapedia.com
  • 6. RIA Characteristics • Full applications • Could replace desktop apps • Applications, not web pages
  • 7. What’s in it for me? for my employer?
  • 8. “ Rich Internet Applications are the next evolution of the web. ” Source: Gartner Research, May 11, 2005
  • 9. Builds on existing skills and knowledge
  • 10. $
  • 11. Saved ~160 GB in 3 hrs
  • 12. User experience matters
  • 13. Client Options • Ajax (In Browser) • Java (Sun) • XUL (Mozilla) • XAML (Microsoft) • MXML (Adobe Flex)
  • 14. Ajax Examples
  • 15. XUL Examples
  • 16. XUL Examples Songbird
  • 17. XAML Examples
  • 18. 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?
  • 19. PHP and RIAs • Read in XML from a PHP backend (REST)
  • 20. 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>”; ?>
  • 21. PHP and RIAs • Transfer PHP objects to the client directly • JSON - JavaScript Object Notation • AMF - ActionScript Messaging Format
  • 22. JSON and PHP
  • 23. Flex with AMFPHP <?php //connect to the database mysql_connect ... //get the data $ResultObject = mysql_query( “SELECT * from recipes”); ... return( mysql_fetch_object( $ResultObject ) ); ?>
  • 24. How to make money?
  • 25. How to make money?
  • 26. 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
  • 27. What’s next?
  • 28. 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
  • 29. 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
  • 30. THANK YOU!
