我来为您提供 PHP 项目的 Dockerfile 编写方案，包含不同场景的配置。

基础 PHP 环境 Dockerfile

基础版（适合简单项目）

# 基础镜像
FROM php:8.2-fpm
# 设置工作目录
WORKDIR /var/www/html
# 安装系统依赖
RUN apt-get update && apt-get install -y \
    git \
    curl \
    libpng-dev \
    libonig-dev \
    libxml2-dev \
    zip \
    unzip \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*
# 安装 PHP 扩展
RUN docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd
# 安装 Composer
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer
# 复制项目文件
COPY . .
# 设置权限（如果使用 Laravel 等框架）
RUN chown -R www-data:www-data /var/www/html \
    && chmod -R 755 /var/www/html/storage \
    && chmod -R 755 /var/www/html/bootstrap/cache
# 暴露端口
EXPOSE 9000
# 启动命令
CMD ["php-fpm"]

生产优化版

FROM php:8.2-fpm-alpine
# 设置工作目录
WORKDIR /var/www/html
# 安装系统依赖（Alpine 版本）
RUN apk add --no-cache \
    git \
    curl \
    libpng-dev \
    libxml2-dev \
    zip \
    unzip \
    && docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd
# 安装 Composer
COPY --from=composer:2 /usr/bin/composer /usr/bin/composer
# 复制项目文件
COPY . .
# 生产环境优化
RUN composer install --optimize-autoloader --no-dev \
    && php artisan optimize \
    && php artisan view:cache \
    && php artisan route:cache
# 设置权限
RUN chown -R www-data:www-data /var/www/html \
    && chmod -R 755 /var/www/html/storage \
    && chmod -R 755 /var/www/html/bootstrap/cache
# 健康检查
HEALTHCHECK --interval=30s --timeout=3s --start-period=5s --retries=3 \
    CMD php-fpm -t || exit 1
EXPOSE 9000
USER www-data
CMD ["php-fpm"]

多阶段构建版

# 第一阶段：构建阶段
FROM composer:2 AS composer
WORKDIR /app
COPY composer.json composer.lock ./
RUN composer install --no-scripts --no-autoloader
COPY . .
RUN composer install --optimize-autoloader
# 第二阶段：运行阶段
FROM php:8.2-fpm-alpine
WORKDIR /var/www/html
RUN apk add --no-cache \
    libpng-dev \
    libxml2-dev \
    && docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd
# 从构建阶段复制
COPY --from=composer /app /var/www/html
RUN chown -R www-data:www-data /var/www/html \
    && chmod -R 755 /var/www/html/storage \
    && chmod -R 755 /var/www/html/bootstrap/cache
EXPOSE 9000
CMD ["php-fpm"]

开发环境版（含 Xdebug）

FROM php:8.2-fpm
WORKDIR /var/www/html
# 安装系统依赖
RUN apt-get update && apt-get install -y \
    git \
    curl \
    libpng-dev \
    libonig-dev \
    libxml2-dev \
    zip \
    unzip \
    nodejs \
    npm \
    && apt-get clean \
    && rm -rf /var/lib/apt/lists/*
# 安装 PHP 扩展
RUN docker-php-ext-install pdo_mysql mbstring exif pcntl bcmath gd
# 安装 Xdebug
RUN pecl install xdebug \
    && docker-php-ext-enable xdebug
# Xdebug 配置
RUN echo "xdebug.mode=debug" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
    && echo "xdebug.start_with_request=yes" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
    && echo "xdebug.client_host=host.docker.internal" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
    && echo "xdebug.client_port=9003" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini \
    && echo "xdebug.idekey=PHPSTORM" >> /usr/local/etc/php/conf.d/docker-php-ext-xdebug.ini
# 安装 Composer
COPY --from=composer:latest /usr/bin/composer /usr/bin/composer
# 复制项目文件
COPY . .
# 设置权限
RUN chown -R www-data:www-data /var/www/html
EXPOSE 9000
CMD ["php-fpm"]

Nginx 配置示例

# nginx/conf.d/app.conf
server {
    listen 80;
    server_name localhost;
    root /var/www/html/public;
    index index.php index.html;
    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }
    location ~ \.php$ {
        fastcgi_pass php:9000;
        fastcgi_index index.php;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include fastcgi_params;
    }
    location ~ /\.ht {
        deny all;
    }
}
