PHP8.0検証ついでにxdebugの警告解消

いつも検証用に使ってるDockerコンテナをPHP8.0にバージョンを上げたので、確認したところ

console

% docker-compose exec app php -v                                                                                                                                                            +[master]

Xdebugが3系に変わったことで、更新があるようです。
UpgradeGuideへのURLをもらえたので参照してphp.iniを修正します。

php.ini

[xdebug]
xdebug.mode=debug
xdebug.client_host=host.docker.internal
xdebug.client_port=9000
xdebug.start_with_request=yes
xdebug.remote_cookie_expire_time=3600
xdebug.log=/tmp/xdebug.log
xdebug.discover_client_host=0

再度実行すると

console

% docker-compose exec app php -v                                                                                                                                                            +[master]
