Install Xdebug
sudo apt-get install php-xdebug php-dev php-curl
sudo apt install php-pear
sudo pecl channel-update pecl.php.net
sudo pecl install xdebug
Create first project

- Try Run / Debug as PHP CLI Application
- You'll be asked to add PHP env
- Click "add" to add a New PHP Executable
- use /usr/bin/php as Executable path
- use system default php.ini
- Click "finish"
- Click "Apply and Close"
- Try Run/Debug as PHP CLI Application again
- Set breakpoints and debug
Create MediaWiki Project
make sure your user is part of group www-data
/var/www/html$ sudo chown www-data.www-data mediawiki-1.33.2
/var/www/html$ sudo chmod g+w mediawiki-1.33.2/
/var/www/html$ sudo chown -R www-data.www-data wiki
Create Eclipse project with "open project from existing source" using /var/www/html/wiki as the source folder
Enable composer in Project's properties There should be only some 20 errors and 60 warnings. Mostly the errors are XMLProblems and ComposerHook ComposerPack issues which are hopefully not relevant.
Debugging
Set your breakpoints e.g. in the code e.g. of an extension. Then click index.php and right click "Run Debug as PHP Web Application". You'll be asked for the URL to debug After clicking "debug" the code will hopefully halt at one of your breakpoints and you can inspect what is going on.
Add Extension to debug
e.g. S5SlideShow
{
"require": {
"wikimedia/at-ease": "*"
}
}
wget https://getcomposer.org/composer.phar
sudo php composer.phar update
Debug Extension
XDebug
/etc/php/7.2/mods-available$ cat xdebug.ini
zend_extension=xdebug.so
xdebug.remote_enable=On
sudo service apache2 restart
try Zend Debugger
