[[https://www.php.net/|PHP]]

===== 环境搭建 =====

==== 纯 PHP 运行环境 ====

可使用 [[docker|Docker]] 进行配置

<code yaml [enable_line_numbers="true"] compose.yml>
services:
  php:
    image: php:8.4-apache
    container_name: php
    restart: unless-stopped
    volumes:
      - ./app:/var/www/html
    networks:
      - web
</code>

随后启动容器

<code bash>
docker compose up -d
</code>

==== 搭配数据库等使用 ====


如需搭配数据库等使用，则需通过 Dockerfile 来构建镜像。例如

''.env'' 文件用于存放环境变量

<code ini [enable_line_numbers="true"] .env>
DB_DATABASE=db
DB_USER=user
DB_ROOT_PASSWORD=root_password
DB_PASSWORD=password
</code>

''Dockerfile'' 文件用于安装 PHP 拓展

<code docker [enable_line_numbers="true"] Dockerfile>
FROM php:8.4-apache

RUN docker-php-ext-install pdo_mysql
</code>

<code yaml [enable_line_numbers="true"] compose.yml>
services:
  php:
    build: .
    container_name: php
    restart: unless-stopped
    volumes:
      - ./app:/var/www/html
    environment:
      DB_HOST: db
      DB_NAME: ${DB_DATABASE}
      DB_USER: ${DB_USER}
      DB_PASSWORD: ${DB_PASSWORD}
    depends_on:
      - db
    networks:
      - web
      - net-int

  db:
    image: mariadb:11
    container_name: db
    restart: unless-stopped
    environment:
      MARIADB_ROOT_PASSWORD: ${DB_ROOT_PASSWORD}
      MARIADB_DATABASE: ${DB_DATABASE}
      MARIADB_USER: ${DB_USER}
      MARIADB_PASSWORD: ${DB_PASSWORD}
    volumes:
      - ./db:/var/lib/mysql
    networks:
      - net-int

networks:
  web:
    external: true
  net-int:
    internal: true
</code>

此时，首次启动（或 ''Dockerfile'' 有任何更改）时需要构建容器

<code bash>
docker compose up -d --build
</code>

后续直接启动容器即可

<code bash>
docker compose up -d
</code>
