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▹ Act like a form

switch ($action) { case 'read': ; break;

default: ; break; }

Code templates (II)

Capable of code completion Set cursor positioning (${cursor}, ${}) Dynamic content by use of variables▹ ${class}▹ ${function}▹ ${variable}▹ ${value}

switch (${dollar}${variable}) { case ${value}: ${cursor}; break;

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 {

private function connect() { return $this->dbHandler->connect(); } }

class docuHint { /** * @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

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)

LoactionLinux / Mac OsX: points to the phpDocumentor installation

Windows: points to the PHP executable

Working directorydirectory to store temporary data

ArgumentsLinux/ 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)

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
