Xdebug.ini Configuration For XDebug Version 3

Settings for XDebug version 3 on the Docker server are specified in xdebug.ini. ,

zend.extension="/usr/local/lib/php/extensions/no-debug-non-zts-20190902/xdebug.so"
xdebug.mode=debug
xdebug.start_with_request=yes
xdebug.remote_port=9003
xdebug.session="PHPSTORM"
xdebug.remote_enable=1
xdebug.client_host=192.168.123.107
xdebug.remote_log="/tmp/xdebug.log"

• zend.extension is the path to the xdebug library that is installed via Dockerfile. If the version of XDebug changes, this path will need to be updated to match the installed library file.
• xdebug.mode enables XDebug.
• xdebug.start_with_request starts the debugger.
• xdebug.remote_port specifies the XDebug port. The default for XDebug version 3 is 9003. This must match the PHPStorm setting under Preferences > PHP > Debug > XDebug > Debug Port. (The default port for version 2 was 9000.)
• xdebug.session specifies the IDE key used the IDE to connect to XDebug. This matches the `IDE Key` setting in PHPStorm's PHP Remote Debug Run Configuration. (xdebug.session replaces xdebug.idekey for XDebug 2.)
• xdebug.client_host specifies the IP of the client running the IDE. (xdebug.client_host replaces xdebug.remote_host for XDebug 2.)

See xdebug.ini settings for XDebug version 2 for legacy settings.
