Docker php:apache HTML/PHP 代码运行不正确。 stack main() 抛出在多个区域
Docker php:apache HTML/PHP code runs incorrectly. stack main() thrown in multiple areas
感谢您花时间阅读这个问题。我用 PHP、HTML、CSS 编写了代码，
Javascript 和 MySQL 在开发计算机上。此代码运行良好。没有显示错误。
我想将我的代码移动到 docker 群中。我制作了一个 docker 组合文件（图 1）并启动
我的 docker swarm 规格显示（图 2）。群堆栈运行完美但是当我去添加
我的代码连接到 /var/www/html 它显示不正确，错误时出错
(图 3).
我试图提供任何有价值的信息来破解这个问题。如果有什么我
丢失或信息太多？！？让我知道。
提前致谢。

您用于 Web 容器的 Docker 图像至少没有启用 mysqli 插件（因此是未定义的函数）。您可以在官方 PHP 基本映像中使用 docker-php-ext-install 和 docker-php-ext-enable 在 Docker 文件中启用它。
RUN docker-php-ext-install mysqli && docker-php-ext-enable mysqli
https://github.com/docker-library/docs/tree/master/php#php-core-extensions
https://github.com/docker-library/php/issues/391
一旦解决，可能还有其他问题，但这是眼前的问题。
问题已解决。
原来制作我的应用程序需要mysqli 运行（默认没有安装！）。
谢谢大家
