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.

1. 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.

2. 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.

3. 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.

4. 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.

5. 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';

6. 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.

7. 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.

8. 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.
