Composer包管理 #

一、安装Composer #

bash

curl -sS https://getcomposer.org/installer | php
mv composer.phar /usr/local/bin/composer

二、composer.json #

json

{
    "name": "app/myapp",
    "require": {
        "monolog/monolog": "^2.0"
    },
    "autoload": {
        "psr-4": {
            "App\\": "src/"
        }
    }
}

三、常用命令 #

bash

composer install
composer update
composer require vendor/package
composer dump-autoload

四、自动加载 #

php

<?php
require 'vendor/autoload.php';

use App\Models\User;

$user = new User();
