我有一个Laravel环境通过Mac OS X Big Sur上的Sail在Docker上运行。我添加了一个phpmyadmin到我的docker-compose.yml文件中，它一切正常，但当我尝试将数据导入到数据库时，我得到：

Warning: POST Content-Length of 68109047 bytes exceeds the limit of 2097152 bytes in Unknown on line 0

我将docker配置文件发布到我的Laravel项目并重新启动了docker。

以及在docker/8.1/php.ini中的文件

post_max_size = 100M
upload_max_filesize = 100M
variables_order = EGPCS

但仍然没有运气。我也试着运行这个命令，然后在提示符：

sail php -a
phpinfo();

其中透露了这一点：

Configuration File (php.ini) Path => /etc/php/8.1/cli
Loaded Configuration File => /etc/php/8.1/cli/php.ini

但是在我的/etc文件夹中没有php文件夹。我在我的docker配置中也注意到了这一点，在docker/8. 1/Dockerfile

COPY supervisord.conf /etc/supervisor/conf.d/supervisord.conf
COPY php.ini /etc/php/8.1/cli/conf.d/99-sail.ini
RUN chmod +x /usr/local/bin/start-container

但是，这里也没有/etc/php文件夹
