DESCRIPTION
Integrated development plattforms (IDEs) like Eclipse or Netbeans do get more popular these days. One cause might be the beautiful benefits a developer gains from using an IDE like a type history or a code completion. This talk shall enable the attendee to get knowleadge about the possibilites of Eclipse PDT to use xDebug as internal debugger It shows howto install xDebug and give a deep introduction about how to enable Eclipse PDT version 2 to communicate with xDebug. Another topic of this talk would be the different debugging mechanism Eclipse PDT provides and how they work.

Installation Configuration Techniques Eclipse PDT Troubleshooting
Obtaining Xdebug - Linux
#> sudo apt-get install php5-xdebug ↵
#> php -v ↵
PHP 5.2.-3ubuntu4.2 with Suhoshin-Patch 0.9.6.2 (cli)Copyright © 1997-2008 The PHP GroupZend Engine v2.2.0, Copyright © 2002-2008 Zend Technologies with Xdebug v2.0.5, Copyright © 2002-2008, by Derick Rethans
Easiest way on Linux systems Basic configuration
Obtaining Xdebug - PECL
#> sudo pecl install xdebug ↵
Still configurations to be done
▹ Add:zend_extension=“/usr/local/php/modules/xdebug.so
to php.ini Ignore notes about to add
„extension=xdebug.so“ → causes problems
Obtaining Xdebug – precompiled Modules
ActiveState
▹ Komodo IDE Xdebug binaries (http://downloads.activestate.com/Komodo/releases/5.2.2/remotedebugging)
Configuration
Add to php.ini
[XDebug] ;; Only Zend OR (!) XDebug zend_extension="/usr/local/php/modules/xdebug.so"
[XDebug] ;; Only Zend OR (!) XDebug zend_extension="/usr/local/php/modules/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
Configuration (II)
