[Laravel] 01 - Love beautiful code? We do too.

   php --version
   sudo apt-get update
   sudo add-apt-repository ppa:ondrej/php
   sudo apt-get install python-software-properties
   sudo apt-get update
   sudo apt-get install php7. # For PHP 7.0

   php --version

安装 Composer

Goto: https://getcomposer.org/download/

执行 Download Composer 的内容。

# 查看composer安装结果
lolo@lolo-UX303UB$ php composer.phar

配置 Laravel

当然，具体要求要看：https://laravel.com/docs/5.6

[1] 可能遇到的zip的安装问题：http://opencode.co.kr/php_tips/255，解决方案：

# For php v7.
sudo apt-get install php7.-zip
 
# For php v7.
sudo apt-get install php7.-zip

[2] 配置没问题就可以成功安装laravel。

unsw@unsw-UX303UB$ php composer.phar global require "laravel/installer"

[3] 安装结果，多了vendor文件夹。

[4] 安装结果，有了laravel文件夹

四、第一个 Laravel 项目

安装日志

Problem 1: requires ext-mbstring

sudo apt-get install php7.-mbstring

Problem 2: requires ext-dom

sudo apt-get install php7.-xml

运行 Laravel 项目

lolo@lolo-UX303UB$ ls
app      bootstrap      composer.lock  database      phpunit.xml  readme.md  routes      storage  vendor
artisan  composer.json  config         package.json  public       resources  server.php  tests    webpack.mix.js
 
lolo@lolo-UX303UB$ php artisan serve
Laravel development server started: <http://127.0.0.1:8000>

五、框架基本思路

框架执行过程，以及显示Hello world的过程。

app       -- Https 业务逻辑
 
          -- Http/routes.php【返回 (1) view　--> resources/views/welcome.blade.php】
 
bootstrap -- 框架启动，自动加载
 
          -- autoload.php【加载 (1) /../vendor/autoload.php】
 
          -- app.php【实例化 (2) app and then return $app】
 
config    -- 配置文件，such as cache.
 
database -- 数据库相关资源
 
public    -- 静态资源, such as pic.
 
          -- index.php【加载 (1) /../bootstrap/autoload.php then (2) app.php】
 
resources -- 视图以及原始的资源文件，views就是mvc中的v
 
          -- views/welcome.blade.php【显示的首页 (2) html内容】
 
storage   -- 编译后的模板文件等。
 
tests     -- 单元测试。
 
vendor    -- 依赖模块

项目配置

一、常见包管理器

Java:        Maven
NodeJS:      NPM
Objective-C: CocoaPods
PHP:         PEAR

However，

Composer 是依赖管理工具，不是包管理器。

Install，

Goto: [Laravel] 01 - Love beautiful code? We do too.

二、使用 composer

创建composer.json

$ composer init

开始生成并配置：composer.json

查看要安装的包

有么？$ composer search monolog

版本？$ composer show monolog/monolog

列出所有相关信息，包括版本：$ composer show -- all monolog/monolog

包设置并安装

$ composer install

vendor 所有composer安装的目录，monolog就在里面。

自动安装依赖

composer require：自动安装相关的依赖，如下所示。

三、使用 Laravel

安装Laravel

因为laravel本质就是个“包”。

$ composer search laravel

生成Laravel项目

有三种方式：

$ php composer.phar create-project --prefer-dist laravel/laravel laravel01

$ laravel new laravel02

$ laravel new test --dev

四、Artisan 控制台

一个命令行工具

[1] 生成一个新项目

$ laravel new laravel53

localhost:8888/laravel53/public/

[2] 打开项目by PhpStorm

[3] 命令行进入项目主路径

[4] 查看有哪些命令：

$ php artisan

$ php artisan list

$ php artisan help migrate

命令行的使用

例如：创建控制器的效果，生成了StduentController.php
