Let's talk about the steps to implement the laravel5.5 project
Laravel is a simple, elegant, and highly development-efficient PHP framework designed to build web applications and APIs. It is widely used in web development and is known for its development speed and good code structure.
In this article, we will learn how to use the laravel5.5 framework to implement a project. We will use the MVC (Model-View-Controller) pattern to build our application and use Composer to manage dependencies.
- Preparation
Before you begin, you need to install PHP 7.0 or higher and a MySQL database. You will also need to install Composer, which is a PHP package manager that we will use to install the required dependencies in our project.
- Create Laravel Project
First, open a terminal and go to the directory where you want to create the project. Then use the following command to create a new Laravel project:
composer create-project --prefer-dist laravel/laravel project_name
This will download and install laravel, the required dependencies, and some default files and folders. Note that project_name
is the name of the project you want to create.
- Configuring Database
Laravel uses a SQLite database by default, but we will use a MySQL database here. To do this, open the .env
file and change the following lines:
DB_CONNECTION=mysql DB_HOST=127.0.0.1 DB_PORT=3306 DB_DATABASE=your_database_name DB_USERNAME=your_database_username DB_PASSWORD=your_database_password
Note that changing your_database_name
, your_database_username
and your_database_password
to reflect your actual database credentials.
- Create Database Table
Before we continue writing code, let’s create the database table. We will use laravel's migration feature to achieve this. Create a migration using the following command:
php artisan make:migration create_tasks_table --create=tasks
This will create a migration named create_tasks_table
which will create a table named tasks
in the database. Open the migration file and add the following code in the up
method to define the table structure:
public function up() { Schema::create('tasks', function (Blueprint $table) { $table->increments('id'); $table->string('name'); $table->text('description'); $table->timestamps(); }); }
The table has an auto-incrementing ID column, name and description columns, and timestamp column.
Now, run the following command to create the table:
php artisan migrate
This will run the migration and create the table in the database.
- Create a task model
Next, we will create a task model. In Laravel, a model is a class associated with a database table. Create a model named Task
using the following command:
php artisan make:model Task
This will create a Task.php
file in the app
directory with Contains a basic blank model.
Open the file and add the following lines to define the association with the tasks
table:
protected $table = 'tasks';
- Create Controllers and Views
The next step is to create the controller and view. Controllers are the main business logic of the application and render views or JSON responses. In Laravel, we use controllers to handle routing in our application.
Create a controller named TaskController
using the following command:
php artisan make:controller TaskController --resource
This command will create the TaskController.php
file and route it according to RESTful Conventions define various methods.
Now, we need to create a view for each route. Create a view file named index.blade.php
using the following command:
touch resources/views/tasks/index.blade.php
In that file, add the following content to the HTML:
@extends('layouts.app') @section('content') <div class="container"> <div class="row justify-content-center"> <div class="col-md-8"> <div class="card"> <div class="card-header">Tasks</div> <div class="card-body"> <table class="table"> <thead> <tr> <th scope="col">#</th> <th scope="col">Name</th> <th scope="col">Description</th> <th scope="col">Created At</th> <th scope="col">Updated At</th> </tr> </thead> <tbody> @foreach ($tasks as $task) <tr> <th scope="row">{{$task->id}}</th> <td>{{$task->name}}</td> <td>{{$task->description}}</td> <td>{{$task->created_at->toFormattedDateString()}}</td> <td>{{$task->updated_at->toFormattedDateString()}}</td> </tr> @endforeach </tbody> </table> </div> </div> </div> </div> </div> @endsection
This view All tasks will be displayed in a table.
Next, we need to update the controller to present this view and extract the task data. Open the TaskController.php
file and add the following to the index
method:
public function index() { $tasks = Task::all(); return view('tasks.index', compact('tasks')); }
This will extract all tasks and pass them to the view to display them.
- Routing
Now, we need to configure our routing into our application. Open the routes/web.php
file and add the following route:
Route::get('/', 'TaskController@index');
This will map the root route to the index
method of TaskController
.
- Running the Application
Now that we are done writing and configuring our application, let’s run it! Start the application using the following command:
php artisan serve
Navigate to http://localhost:8000
in your browser and you should be able to see all the tasks in your application.
Conclusion
In this article, we learned how to use the laravel5.5 framework to build a simple application. We cover the initial Laravel development process, including how to set up dependencies using Composer, how to configure the database, how to create models and migrations, and how to create controllers and views and map them to routes. This is a very simple example, but you can extend it into your own application by exploring more documentation and resources.

Both Django and Laravel are full-stack frameworks. Django is suitable for Python developers and complex business logic, while Laravel is suitable for PHP developers and elegant syntax. 1.Django is based on Python and follows the "battery-complete" philosophy, suitable for rapid development and high concurrency. 2.Laravel is based on PHP, emphasizing the developer experience, and is suitable for small to medium-sized projects.

Laravel is a PHP framework for easy building of web applications. It provides a range of powerful features including: Installation: Install the Laravel CLI globally with Composer and create applications in the project directory. Routing: Define the relationship between the URL and the handler in routes/web.php. View: Create a view in resources/views to render the application's interface. Database Integration: Provides out-of-the-box integration with databases such as MySQL and uses migration to create and modify tables. Model and Controller: The model represents the database entity and the controller processes HTTP requests.

How does Laravel play a role in backend logic? It simplifies and enhances backend development through routing systems, EloquentORM, authentication and authorization, event and listeners, and performance optimization. 1. The routing system allows the definition of URL structure and request processing logic. 2.EloquentORM simplifies database interaction. 3. The authentication and authorization system is convenient for user management. 4. The event and listener implement loosely coupled code structure. 5. Performance optimization improves application efficiency through caching and queueing.

PHP and Laravel are not directly comparable, because Laravel is a PHP-based framework. 1.PHP is suitable for small projects or rapid prototyping because it is simple and direct. 2. Laravel is suitable for large projects or efficient development because it provides rich functions and tools, but has a steep learning curve and may not be as good as pure PHP.

Laravel provides a comprehensive Auth framework for implementing user login functions, including: Defining user models (Eloquent model), creating login forms (Blade template engine), writing login controllers (inheriting Auth\LoginController), verifying login requests (Auth::attempt) Redirecting after login is successful (redirect) considering security factors: hash passwords, anti-CSRF protection, rate limiting and security headers. In addition, the Auth framework also provides functions such as resetting passwords, registering and verifying emails. For details, please refer to the Laravel documentation: https://laravel.com/doc
