Laravel to get you up and running. 2. Getting started To get started with Laravel, you need to set up your PHP environment on your computer. You can do this in various ways. Before going on, remove called environment variables, for your app: 9 For example in this portion of the file you can see we set the app name, the debug flag, the URL, settings related to logging, to the database connection, email config/app.php file: 10 Each file in the folder contain a lot of configuration options you can set, very well documented. What’s the difference between config files and the .env file? Environment

repository. This repository has no external dependencies. Having a convenient, centrally located set of interfaces you may use for decoupling and dependency injection will serve as an easy alternative Copy the new .env.example file to .env , which is the 5.0 equivalent of the old .env.php file. Set any appropriate values there, like your APP_ENV and APP_KEY (your encryption key), your database config/database.php configuration file. Set the config files in the config/ directory to represent either the values that are consistent across all of your environments, or set them to use env() to load values

 Replace the laravel folder. Laravel 3.2.1  Fixed bug in cookie retrieval when cookie is set on same request.  Fixed bug in SQL Server grammar for primary keys.  Fixed bug in Validator models with Twig.  Allow multiple views to be registered for a single composer.  Added Request::set_env method.  Schema::drop now accepts $connection as second parameter.  Added Input::merge controller factories for injecting any IoC.  Added link_to_action HTML helpers.  Added ability to set default value on Config::get.  Added the ability to add pattern based filters.  Improved session

在系统的任意位置创建一个批处理文件 homestead.bat： @echo off set cwd=%cd% set homesteadVagrant=C:\Homestead cd /d %homesteadVagrant% && vagrant %* cd /d %cwd% set cwd= set homesteadVagrant= 你需要将脚本中实例路径 C:\Homestead //$store_result = $photo->store('photo'); $store_result = $photo->storeAs('photo', 'test.jpg'); $output = [ 'extension' => $extension, 'store_result' => $store_result $store_result ]; print_r($output);exit(); } exit('未获取到上传文件或上传过程出错'); }); 我们还是使用 Advanced REST Client 工具来演示 POST 表单提交： 本文档由 Laravel 学院提供 Laravel 学院致力于提供优质 Laravel

Laravel 才会加载其服务提供者。 服务容器 1、简介 Laravel 服务容器是一个用于管理类依赖和执行依赖注入的强大工具。依赖注入听上去很花 哨，其实质是通过构造函数或者某些情况下通过 set 方法将类依赖注入到类中。 让我们看一个简单的例子： set votes = 100 where name = ?', ['John']); 运行删除语句 delete 方法用于删除数据库中已存在的记录，和 update 一样，该语句返回被删除的行 方法定义一个在所有其他授权检查之后运行的回调，所不同的是， 在 after 回调中你不能编辑授权检查的结果： $gate->after(function ($user, $ability, $result, $arguments) { // }); 3、检查权限（Abilities） 通过 Gate 门面 权限定义好之后，可以使用多种方式来“检查”。首先，可以使用 Gate
