php - 带有 Xdebug 3 env XDEBUG_MODE 的 Docker PHP 不起作用

Question

我正在尝试配置 Xdebug 3在 PHP 容器中，并设置 XDEBUG_MODE环境变量为 off根据文档 https://xdebug.org/docs/all_settings#mode但是 xdebug_info()显示 mode=develop .怎么修？
Dockerfile:

FROM php:7.4.11-fpm
…
ENV XDEBUG_MODE=off
ENV XDEBUG_CONFIG=""
RUN pecl install xdebug \
    && docker-php-ext-enable xdebug \
...

docker -compose.yml:

services:
  php:
    build:
      dockerfile: ${PWD}/.devcontainer/Dockerfile
    image: php-fpm
    environment:
      XDEBUG_MODE: ${XDEBUG_MODE} // off
      XDEBUG_CONFIG: ${XDEBUG_CONFIG}

xdebug 信息:

php -r 'xdebug_info();'

xdebug.mode => develop => develop

更新:
我的案例:我使用 VSCode 来调试我的应用程序，所以只有在 Xdebug 监听处于事件状态时才需要打开 Xdebug 模块。更好的方法是使用 env XDEBUG_CONFIG 和 XDEBUG_MODE，因为它不需要更改 ini 文件。

它确实有效。我的意思是:实际行为/最终结果。
尽管它显示 xdebug.mode => develop实际功能全部关闭:

Feature => Enabled/Disabled
Development Aids => ✘ disabled
Coverage => ✘ disabled
GC Stats => ✘ disabled
Profiler => ✘ disabled
Step Debugger => ✘ disabled
Tracing => ✘ disabled

我已经在 Windows 10 上进行了本地测试 .. 我看到了同样的结果:
php.ini 有

xdebug.mode = debug

没有 XDEBUG_MODE override cmd 显示调试器已按应有的方式启用:

Feature => Enabled/Disabled
Development Aids => ✘ disabled
Coverage => ✘ disabled
GC Stats => ✘ disabled
Profiler => ✘ disabled
Step Debugger => ✔ enabled
Tracing => ✘ disabled
...
xdebug.mode => debug => debug

与 XDEBUG_MODE覆盖:

C:\Users\Andriy
$ SET XDEBUG_MODE=off

C:\Users\Andriy
$ php -r "xdebug_info();"

...
Feature => Enabled/Disabled
Development Aids => ✘ disabled
Coverage => ✘ disabled
GC Stats => ✘ disabled
Profiler => ✘ disabled
Step Debugger => ✘ disabled
Tracing => ✘ disabled
...
xdebug.mode => debug => debug

如果我运行这个命令(传递额外的 Xdebug 配置参数，告诉立即开始调试):

php -dxdebug.start_with_request=yes -r "xdebug_info();"

然后在没有覆盖的情况下，它将尝试建立调试连接，而在没有覆盖的情况下，它不会尝试这样做。这证实了覆盖有效(至少在我的环境中)。
