In late december 2008 the Eclipse Foundation and the PDT developer team released the Eclipse PHP Development Platform version 2.0. This release comes with a number of enhancements and improvements to the prior version of PDT. This talk is about these changes. It also gives you an introduction how to prepare your Eclipse PDT workspace to be an accessible and provding companion for your daily work by integrating xDebug, subversive and phpDocumentor using the external tools platform.

3. Agenda
 Installation
 Views & Perspectives
 Projects
 Templates
 Code completion
 What's new?
 Tips & Tricks
 External Tools Framework
 xDebug integration
 Plugins

4. Installation
 Download latest revision from Eclipse website
(http://www.eclipse.org/pdt/downloads)
▹ All in one (recommended):
provides everything you need to run PDT
▹ PDT Feature / Update Manager:
extends an existing Eclipse, but all dependencies PDT
relies on needs to be installed first.
 Extract archive
 Copy to favorized location
(e.g. /usr/local/bin/ or another location in your application path)

5. Views & Perspectives
 Perspective
(Window > Open Perspektive)
▹ Arrangement of Views:
PHP Perspektive contains e.g. 'PHP Explorer',
'Outline' and 'Project Outline'
 Views or Tabs
(Window > Show View)
▹ Viewport providing specific information and/or
functionality

6. Views & Perspectives (II)

7. Projects
 Organizational untis
 Customizable
configuration
 PHP include path
▹ Validation
 Build rules
▹ included resources
▹ excluded resources

8. Templates
 Contextual predefined
code snippets
 Configure at
Preferences > PHP >
Templates

9. Code templates
 Activation key:
<CTRL> + space
 Code templates
▹ Eases typing of complex code structures
(e.g. switch – statement)
▹ Minimize errors
switch ($action) {
▹ Act like a form case 'read':
;
break;
default:
;
break;
}

10. Code templates (II)
 Capable of code completion
 Set cursor positioning (${cursor}, ${})
 Dynamic content by use of variables
▹ ${class} switch (${dollar}${variable}) {
▹ ${function} case ${value}:
${cursor};
▹ ${variable} break;
▹ ${value}
default:
;
break;
}

11. File templates
 File templates
▹ Create new files with
standardized
structures
▹ Easy to create or
adapt

12. Code completion
(Code Assist)
 Configuration via
Preferences > PHP > Editor > Code Assist

13. Code completion (II)
(Code Assist)
 Activation key
<CTRL> + space
 Completes
▹ PHP functions
▹ Classes & functions
▹ Constants
▹ Code templates
 Evolves with every plugin supporting this
feature (e.g. JSEclipse)

14. Code completion (III)
(Code Assist)

15. Code completion (IV)
(Code Assist)
 Documentation hint
▪ declaring the name of a class to be instantiated as the
type of the 'local' class var will enable Eclipse to resolve
the methods of the instantiated class:
class docuDb { class docuHint {
private function connect() { /**
return $this->dbHandler->connect(); * @var docuDb Database handling
} */
} private $dbHandler = NULL;
private function connectToDB() {
$this->dbHandler = &new docuDb();
$dbh = $this->dbHandler->connect();
}
}

available:
▹ Ant build files
▹ Everything else

20. External Tools Framework (II)

xdebug.remote_enable=true
xdebug.remote_host=127.0.0.1 ;if debugging on remote server, put client IP here
xdebug.remote_port=9000
xdebug.remote_handler=dbgp
;; profiler
xdebug.profiler_enable=Off
xdebug.profiler_enable_trigger=On
xdebug.profiler_output_dir=/data_lokal/temp/xdebug/profiling
 or .htaccess - file
#-------------------------------#
# xDebug section #
#-------------------------------#
php_value xdebug.remote_enable 1
php_value xdebug.remote_handler bdgp
php_value xdebug.remote_host 127.0.0.1 ;if debugging on remote server, put client IP here
;; php_value xdebug.allowed_clients <client IP address>
php_value xdebug.remote_port 9000
