安装composer
到 官网下载composer.phar文件
Mac 或 Linux 系统:
打开命令行窗口并执行如下命令将前面下载的 composer.phar文件移动到 /usr/local/bin/目录下面:
# mv composer.phar /usr/local/bin/composer
注:如果不是以root身份操作,要给/usr/local/bin/composer执行权限
Windows 系统:
1 找到并进入 PHP 的安装目录
2 将 composer.phar 复制到 PHP 的安装目录下面,也就是和 php.exe 在同一级目录。
3 在 PHP 安装目录下新建一个 composer.bat 文件,并将下列代码保存到此文件中。
@php "%~dp0composer.phar" %*
配置使用国内镜像:
1 全局配置(推荐方式)
打开命令行窗口(windows用户)或控制台(Linux、Mac 用户)并执行如下命令:
composer config -g repo.packagist composer https://packagist.phpcomposer.com
2 单个项目配置
修改当前项目的 composer.json配置文件:
打开命令行窗口(windows用户)或控制台(Linux、Mac 用户),进入你的项目的根目录(也就是 composer.json文件所在目录),执行如下命令:
composer config repo.packagist composer https://packagist.phpcomposer.com
或
在当前项目中的 composer.json文件的末尾添加镜像的配置信息
"repositories": { "packagist": { "type": "composer", "url": "https://packagist.phpcomposer.com" }}

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
