1 Desktop Apps with PHP and Titanium Ben Ramsey TEK X May 19, 2010

2 Hi, I m Ben. joind.in/1576

3 DISCLAIMER: I m not a salesman & I don t work for Appcelerator.

4 DISCLAIMER: I helped with the initial embedding of PHP in Titanium.

5 What is Titanium?

8 Four main parts of Titanium apps The html/css/javascript code that makes up the core application logic and UI The APIs that access native device/ desktop functionality, analytics or other modular functionality The language-os bridge that compiles web code into native application code The run-time shell that packages the application for cross-platform distribution

9 Contrasting with AIR... Titanium is released under an open source license Titanium provides access to native controls Titanium applications are packaged for a target system: Windows, OS X, Linux

10 Who is Appcelerator?

12 Appcelerator s role Developed and own s Titanium source Licenses Titanium under Apache license Support, training, and consulting Analytics and tracking Infrastructure for building and packaging releases of your apps in the cloud

13 How Appcelerator makes money...

14 So, why PHP on Titanium?

15 Titanium already had modules to support Python and Ruby development PHP was on their roadmap PHP is a natural scripting complement to other web technologies It was cool and fun to do I can now build desktop apps with PHP without using PHP-GTK (no offense to the maintainers of PHP-GTK)

16 Using Titanium Developer

20 Fill out your application details Click Create Project Click the Test & Package tab Click the Launch App button

22 Now, you have code!

23 Installation on Linux There is a known issue with the GTK libraries for Titanium Developer on Linux Until there is a fix, do this after installing Titanium Developer: cd ~/.titanium/runtime/linux/1.0.0 rm libgobject* libgthread* libglib* libgio*

24 Hello, World.

26 <html> <head> <title>hello, World!</title> </head> <body> <h1>hello, World!</h1> </body> </html>

29 var mainmenu = Titanium.UI.createMenu(); mainmenu.appenditem(titanium.ui.createmenuitem("file")); var menu = Titanium.UI.createMenu(); menu.appenditem(titanium.ui.createmenuitem("quit", function() { if (confirm("are you sure you want to quit?")) { Titanium.App.exit(); } })); mainmenu.getitemat(0).setsubmenu(menu); Titanium.UI.currentWindow.menu = mainmenu;

31 Titanium provides APIs... API Analytics App Codec Database Desktop Filesystem JSON Media Network Notification Platform Process UI UpdateManager Worker

32 Drop in external libraries

33 Accessing these APIs and libraries JavaScript Python Ruby PHP

34 PHP in Titanium

35 <script type="text/php"> // PHP code goes here </script>

36 JavaScript <script type="text/javascript"> var heading = document.getelementbyid("title"); heading.innerhtml = "Hello, World!"; </script>

37 PHP <script type="text/php"> $heading = $document->getelementbyid("title"); $heading->innerhtml = "Hello, World!"; </script>

38 phpinfo()

39 <html> <head> <title>php Info</title> <script type="text/php"> date_default_timezone_set('america/chicago'); ini_set('default_charset', 'utf8'); ini_set('display_errors', 'Off'); function getphpinfo() { ob_start(); phpinfo(); return ob_get_clean(); } </script> </head> <body style="background-color: white; padding: 10px;"> <script type="text/php"> $document->write('<pre>'. getphpinfo(). '</pre>'); </script> </body> </html>

40 PHP caveats echo does not work as expected Titanium state transitions (links) do not send requests Pre-processed scripts (.php) are processed at compile/build time Cannot inject classes defined in.php into runtime code with include/require

41 Are some of these bugs? Maybe.

42 Planet PHP Demo

43 Wrapping up... Titanium allows web developers the ability to create desktop apps It builds native applications that you can distribute for a particular OS You can combine PHP with JavaScript (and Python and Ruby) to leverage the best of each language Still some bugs to iron out, but that s why they need lots of people using it

44 Questions?
