This document discusses using the Eclipse IDE with PHP development. It covers installing Eclipse PDT, configuring views and perspectives, managing PHP projects, using code templates and completion, integrating xDebug for debugging, and several useful plugins like Subclipse for SVN integration. The presentation provides an overview of key PHP development features in Eclipse.

3. Agenda
 Installation
 Configuration
 Views & Perspectives
 Projects
 Templates
 Code competetion
 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. Configuration
 Heap space (memory allocated by JVM)
size depends on system memory capacity
▹ Xms, Xmx
▹ XXMaxPermSize, XXPermSize
 Eclipse PDT settings
▹ disable code folding
▹ formatting / linebreaks
▹ validation / build settings
▹ disable automatic updates

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

7. Views & Perspectives (II)

8. Projects
 Organizational untis
 Customizeable
configuration
 PHP include path
▹ Validation
▹ Build rules
▹ ...

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

10. 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;
}

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

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

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

14. 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)

15. Code completion (III)
(Code Assist)

16. 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 mysql_connect_db(); * @var docuDb Database handling
} */
} private $dbHandler = NULL;
private function connectToDB() {
$this->dbHandler = &new docuDb();
$dbh = $this->dbHandler->connect();
}
}

17. External Tools Framework
 Enables Eclipse to run ,stand-alone'
applications
 Two broad classes of external tools are
available:
▹ Ant build files
▹ Everything else

18. External Tools Framework (II)

19. External Tools Framework (III)
 Loaction
Linux / Mac OsX: points to the
phpDocumentor installation
Windows: points to the PHP executable
 Working directory
directory to store temporary data
 Arguments
Linux/ Mac OsX: command line parameters
to be passed to phpDocumentor.
Windows: path to the phpDocumentor
installation and command line parameters
(e.g.: quot;D:xamppphpphpdocquot; -c quot;$
{project_loc}/doc/tech/config/phpdoc.iniquot;
)

20. External Tools Framework (III)
 Display in favorits
menu
 Standard input &
output

21. xDebug
 Debugging for PHP by Derick Rethans
(http://www.xdebug.org)
 Provides profiling, tracing, code coverage, …
 Cross platform

22. xDebug configuration
 Add to php.ini (e.g. on Mac)
[XDebug]
;; Only Zend OR (!) XDebug
zend_extension=quot;/Applications/xampp/xamppfiles/lib/php/php5/extensions/no-debug-non-zts-
20060613/xdebug.soquot;
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
# profiler
php_value xdebug.profiler_enable_trigger 1
php_value xdebug.profiler_enable 0
php_value xdebug.profiler_output_dir quot;/data_lokal/temp/xdebug/profilingquot;
