Bagaimana untuk Memasang dan Menggunakan Pakej Komposer dalam Projek PHP?

As in my last post, I explained how to install and use Composer in PHP. Today, we will learn how to install Composer packages in a PHP project. The packages we need to install are collections and pestphp/pest.

Searching for Packages

• Open your browser and navigate to ( https://packagist.org/ )

• Search for collections. Scroll down to find the illuminate/collections package. We will install this package.

Installing Package

Open your terminal and run the composer command to check if Composer is installed. If it is, run composer search collections to search for the collections package a list of collection packages is available. Then, run composer require illuminate/collections to install the package.

Using Package

To use package we have to create a new file playground.php in the public directory and add the following code to filter the numbers less then or equal to 5:

<?php
use Illuminate\Support\Collection;
require __DIR__.'/../vendor/autoload.php';

$numbers = new Collection([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);
$lessThanOrEqualTo5 = $numbers->filter(fn($number) => $number <= 5);

var_dump($lessThanOrEqualTo5);

Run php public/playground.php in the terminal to see the output of filtered numbers.

Installing Pest Package

To install the pestphp/pest package, run composer search test a list of test packages show on screen and select one of the test packages. Then, run composer require pestphp/pest --dev to install the package as a development dependency.

Configuring Pest Package

For configuration of pest package run php vendor/bin/pest --init command. This will update the composer.json file as:

{
    "name": "admin/demo",
    "authors": [
        {
            "name": "Ghulam Mujtaba",
            "email": "mujtabaofficial247@gmail.com"
        }
    ],
    "require": {
        "illuminate/collections": "^11.16"
    },
    "autoload": {
        "psr-4": {

            "Core\\": "Core/"  ,
        "Http\\": "Http/"          }
    
    },
    "require-dev": {
        "pestphp/pest": "^2.34"
    },
    "config": {
        "allow-plugins": {
            "pestphp/pest-plugin": true
        }
    }
}

and create a new directory tests with a file ExampleTest.php.

<?php

test('example', function(){

    expect(true)->toBeTrue();
});

Running Tests

We have to run php vendor/bin/pest command in the terminal to see the output of the test file. If you replace true with false, you will see an error message.

Binding Test

Let's take a local binding test for container as something is resolved from this. So, Rename the file ContainerTest.php and replace the code with:

<?php
use Core\Container;
test('it can resolve something out of the container', function () {
    $container = new Container();
    $container->bind('foo', fn()=> 'foo');
    $result = $container->resolve('foo');
    expect($result)->toEqual('foo');
});

To test run php vendor/bin/pest command again in terminal/prompt it shows output as there is no error in file

I hope that you have clearly understood it.
