Laravel is a web application framework based on PHP. It is an excellent framework developed by Taylor Otwell. Laravel has concise, elegant syntax and powerful functions, making web development easier. Below, we will introduce the steps of Laravel website development.

1. Environment Settings

Before starting Laravel development, you need to configure the PHP environment and install Composer. The operating environment of Laravel requires PHP version 5.5.9 and above, and the extension packages Mcrypt and OpenSSL need to be installed. Installation and management are performed through Composer, which can easily manage and reference each dependent package.

2. Laravel installation and configuration

1. Install Laravel

Laravel使用Composer作为依赖管理工具，可以通过以下命令安装Laravel：

`composer create-project --prefer-dist laravel/laravel blog`

这里创建了一个名为blog的Laravel项目。

2. Configure database

在项目的根目录下有一个.env文件，可以用来配置默认的数据库连接、Web应用密钥、邮件设置等信息，需要根据实际情况进行修改。

```
DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=homestead
DB_USERNAME=homestead
DB_PASSWORD=secret
```

Copy after login

3. Generate application key

Laravel需要生成一个应用密钥用于加密生成的凭证和其他元素。可以使用如下命令生成：

`php artisan key:generate`

Copy after login

3. Routing settings

Laravel’s routing settings are relatively flexible and can be achieved by modifying the web.php file in the routes directory. You can use Route::get(), Route::post(), Route::put(), Route::delete() and other methods to configure the corresponding request method.

For example:

Route::get('/home', 'HomeController@index');
Route::post('/login', 'Auth\LoginController@login');

Copy after login

4. Controller settings

The controller is the bridge connecting the model and the view. It can handle user requests and call the model's data operations. method and passed to the view for display. You can create a controller through the following command:

`php artisan make:controller UserController`

Copy after login

Then define various methods in the controller, such as index(), store(), etc.

5. View settings

View is the content displayed to the user, and the view template can be quickly written through the template engine provided by Blade.

For example:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    <title>@yield('title')</title>
</head>
<body>
    @yield('content')
</body>
</html>

Copy after login

6. Model settings

The model usually represents a row or a group of data in the data table. The model can be related to the data table through ORM technology. In conjunction, Laravel provides Eloquent ORM, which can facilitate database operations.

You can create a model through the following command:

`php artisan make:model User`

Copy after login

7. Middleware settings

Middleware can filter or filter user requests before or after they reach the application. Other operations, such as verifying whether the user is logged in, etc.

You can create middleware through the following command:

`php artisan make:middleware CheckAge`

Copy after login

Then define the operation in the handle() method of the middleware.

8. Debugging Tools

Laravel provides some very useful debugging tools that can help developers debug and troubleshoot errors.

For example, Debugbar can display all query requests and response times. You can install it by running the following command in the terminal:

`composer require barryvdh/laravel-debugbar --dev`

Copy after login

Then, add the following configuration in config/app.php:

'providers' => [
    // Other Service Providers
    Barryvdh\Debugbar\ServiceProvider::class,
],

Copy after login

9. Deployment

After development After Laravel is applied, it needs to be deployed. You can install the corresponding version of the PHP environment on the server, and then point the DocumentRoot in the server configuration item to the /public directory of the project.

Finally upload and decompress the file, and set the permissions of the folder.

The above are all the steps for Laravel website development. I hope that through learning, you can become more comfortable in Laravel development.
