php - Docker PHP-Apache 间歇性错误

问题描述

我正在通过一个简单的 PHP 教程学习自动加载。类的代码和自定义自动加载器似乎不是问题。

但是，当它完全没有意义时，我会. . . failed to open stream: No such file or directory in . . .出错。然后我碰巧注意到，当我刷新浏览器几次时，预期的正确输出确实会显示。

因此，它暂时不起作用，然后在几次刷新后就起作用了。我猜它与服务器有关。但是我该如何诊断这个问题呢？

我正在使用以下 docker-compose 文件：

version: "3"

services:
  www:
    image: "php:7.4.24-apache"
    restart: 'always'
    ports:
      - '81:80'
    volumes:
      - ".:/var/www/html"

更新：Docker 日志输出

docker logs --follow complete-object-orient-php-developer-course_www_1 | grep Autoloading
