 Tips & Tricks
 External Tools Framework
 xDebug integration

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)

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

Views & Perspectives (II)

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

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

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;
}

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;
}

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

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

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)

Code completion (III)
(Code Assist)

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();
}
}

What's new in PDT 2.0?
 Less dependencies
 Improved indexing and caching
▹ cleanup of unnecessary depedencies to Java
 Mark occurrences
 Configurable Buildpathes
 Improved code completion
▹ Camelcase matching

What's new in PDT 2.0? (II)
 Enhanced features to support OOP in PHP
▹ Overwrite Indicators

What's new in PDT 2.0? (III)
 Enhanced features to support OOP in PHP
▹ Type & name
hierarchies

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

External Tools Framework (II)

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.: \"D:\\xampp\\php\\phpdoc\" -c \"$
{project_loc}/doc/tech/config/phpdoc.ini\")

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

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

xDebug configuration
 Add to php.ini (e.g. on Mac)
[XDebug]
;; Only Zend OR (!) XDebug
zend_extension=\"/Applications/xampp/xamppfiles/lib/php/php5/extensions/no-debug-non-zts-20060613/xdebug.so\"
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 \"/data_lokal/temp/xdebug/profiling\"

xDebug (III)
 Debug dialog

xDebug (IV)
 Configure PDT to talk to xDebug

xDebug (IV)
 Configure the 'Server' handling the debugging
session

Tips and Tricks (Configuration)
 Heap space (memory allocated by JVM)
size depends on system memory capacity
▹ Xms, Xmx
▹ XXMaxPermSize, XXPermSize
 Eclipse PDT settings
▹ validation / build settings
▹ disable automatic updates
▹ disable code folding

Plugins
 Subclipse
managing SVN repositories from inside Eclipse
 JSEclipse
Provides additional features supporting JavaScript
 Data Tools Platform
managing databases from inside Eclipse

Subclipse (installation)
 Eclipse update site:
http://subclipse.tigris.org/update

Subclipse (configuration)
 Set „auto-properties“
▹ WinXp:
C:\\Dokumente und Einstellungen\\<USER>\\Anwendungsdaten\\Subversion\\config
▹ MacOs / Linux: ~/.subversion/config
[miscellany]
global-ignores = *.o *.lo *.la #*# .*.rej *.rej .*~ *~ .#* .DS_Store .project .cache .settings
enable-auto-props = yes
[auto-props]
*.js = svn:eol-style=LF;svn:keywords=Id LastChangedDate LastChangedRevision URL
*.css = svn:eol-style=LF;svn:keywords=Id LastChangedDate LastChangedRevision URL
*.php = svn:eol-style=LF;svn:keywords=Id LastChangedDate LastChangedRevision URL
*.html = svn:eol-style=LF;svn:mime-type=text/html;svn:keywords=LastChangedDate LastChangedRevision URL
*.htm = svn:eol-style=LF;svn:mime-type=text/html;svn:keywords=LastChangedDate LastChangedRevision URL
*.xsl = svn:eol-style=LF
*.xml = svn:eol-style=LF
*.xsd = svn:eol-style=LF

Subclipse (conflict handling)
 Integrated (diff-) editor to resolve conflicts
 Support for merging changes which do not
conflict
 Preview on the checkout to find conflicts before
updating the sources
