Laravel development: How to get application information using Laravel Tinker?

Laravel is a popular PHP framework that provides a variety of tools to simplify the development process. One very useful tool is Laravel Tinker. This article will introduce how to use Laravel Tinker to get application information.

What is Laravel Tinker?

Laravel Tinker is an interactive CLI tool that uses PsySH as the default shell. It provides an easy way to interact with your Laravel application and monitor the current application status.

When executing code in Laravel Tinker, you have access to all models, controllers, and other classes just like you would in your application. This interactive development approach can bring you many benefits.

Steps to get application information using Laravel Tinker

1. Open a terminal and go to the root directory of your Laravel application.
2. Enter the following command in the terminal to start Tinker:

php artisan tinker

3. You are now in the Tinker interactive shell. You will see a prompt similar to the following:

Psy Shell v0.10.2 ( PHP 7.4.9 — cli) by Justin Hileman

4. In Tinker, you can access any class that has been defined in the application. For example, to get the current time, you can enter the following command:

>>> CarbonCarbon::now()

This will return the current date and time.

5. You can use the $app variable to access the instance of the current application. For example, to get all the options for the current configuration, you can use the following command:

>>> $app['config']->all()

6. You can also access the data in the database. For example, to get the names of all users in the user model, you can use the following command:

>>> AppModelsUser::pluck('name')

7. If you need to perform any of the operations in steps 4, 5, and 6, but you don’t want to do it manually Entering these commands, you can write them into a PHP file and then execute the file in Tinker.

For example, in your application root directory, create a file called functions.php. In the file, write the following code:

<?php

function getAllConfig()
{
    $app = app();
    return $app['config']->all();
}

function getUsersName()
{
    return AppModelsUser::pluck('name');
}

Then, execute the following command to load the file into Tinker:

>>> require_once 'functions.php'

Now, you can use the function getAllConfig()and getUsersName() to get the information you want.

Summary

Laravel Tinker is a very powerful tool that helps you interact with your Laravel application in the command line interface and get information about the current state. By using Tinker, you can develop and debug applications faster because it provides a quick and easy way to access and manipulate your code.
