Laravel is an open source Web application framework based on the PHP language, which is widely used in the development of Web applications. It is known for its simplicity, elegance, expressive syntax and support for the web development process, and has a large community and rich ecosystem, so it is favored by developers.

On Laravel's official website, we can easily find detailed documentation and steps for installing Laravel. Below we will briefly introduce how to start a Laravel project.

1. Install Composer

Laravel uses Composer to manage dependencies, so we need to install Composer first. Enter the following command on the command line to install:

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

After the installation is complete, we can enter the following command to check whether the installation is successful:

composer

2. Install Laravel

Before installing Laravel, we need to create a new directory to save project files. Execute the following command in the command line:

mkdir?mylaravelapp
cd?mylaravelapp

Then we can install the latest version of Laravel through the following command:

composer?create-project?--prefer-dist?laravel/laravel?.

The dot here means that we will install Laravel in the current directory.

After the installation is complete, enter the following command on the command line to start the Laravel project:

php?artisan?serve

This will start a local development server and output the following information on the command line:

Laravel?development?server?started:?http://127.0.0.1:8000

We can enter this address in the browser and see Laravel's welcome interface.

3. Configuring the database

Next, we need to configure the database so that our Laravel application can connect to the database and use it. Find the .env file in the root directory of mylaravelapp and modify the following variable values:

DB_CONNECTION=mysql
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=mylaravelapp
DB_USERNAME=root
DB_PASSWORD=

Here, we use MySQL as the database, the database name is mylaravelapp, the user name is root, and the password is empty.

Then, execute the following command in the command line to generate the Laravel application key:

php?artisan?key:generate

Finally, execute the following command in the command line to perform database migration:

php?artisan?migrate

This Database tables and fields will be created and corresponding relationships created based on the model classes we defined in the application.

4. Create Routes and Views

Now that our Laravel application can connect to the database and is ready to use it, we can create some routes and views to show off data.

Create a new controller in the app/Http/Controllers directory:

php?artisan?make:controller?UserController

Then create an index method in the UserController class:

public?function?index()?{
????$users?=?App\User::all();
????return?view('users',?['users'?=>?$users]);
}

This method will get all User data and pass it into a view called users.blade.php.

Create a new route and add the following code to the routes/web.php file:

Route::get('/users',?'UserController@index');

Finally, create a view named users.blade.php in the resources/views directory File:

@foreach?($users?as?$user)
????<p>{{?$user->name?}}</p>
@endforeach

Now, enter http://127.0.0.1:8000/users in your browser and you will see the names of all users listed.

Summary

Starting a Laravel project requires the following steps:

1. Install Composer
2. Install Laravel
3. Configure database
4. Creating routes and views

Through these steps, we can build a simple Laravel application to display data and implement basic web development. Of course, this is just a simple starting point. Laravel has more functions and features that allow us to develop richer and more complex applications.
