Laravel Composer Installation Guide

As a PHP developer, you must be familiar with Laravel - the popular PHP web application framework. One of the essential tools for working with Laravel is Composer, a dependency manager for PHP.

In this guide, we will walk you through the installation steps for Composer on your machine.

Prerequisites

Before we start, ensure that your machine has the following:

• PHP installed (version 7.2 or higher)
• Command-line interface (CLI) tool
• Access to the internet

Installation steps

Step 1: Download Composer

To install Composer on your machine, you will first need to download the installer. You can do this by running the following command on your CLI:

$ php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"

This will download the installer file 'composer-setup.php' to your current working directory.

Step 2: Verify the installer

To ensure that the downloaded installer is not corrupted, run the following command to verify its SHA-384 hash:

$ php -r "if (hash_file('sha384', 'composer-setup.php') === '669656bab3166a7aff8a7506b8cb2d1c292f042046c5a994c43155c0be6190fa0355160742ab2e1c88d40d5be660b410') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;";

If the installer is verified, you will see the message 'Installer verified' on your screen.

Step 3: Install Composer

To install Composer globally on your machine, run the following command:

$ php composer-setup.php --install-dir=/usr/local/bin --filename=composer

This command will move the 'composer.phar' file to the '/usr/local/bin/' directory and rename it as 'composer'.

Step 4: Verify the installation

To authenticate that Composer is installed successfully, open your CLI and run the following command:

$ composer

You should see the Composer logo, version number, and a list of commands.

Conclusion

Composer is an essential tool for working with Laravel projects. It allows you to manage dependencies, install packages, and streamline your workflow.

By following these steps, you can quickly install Composer on your machine and start working efficiently with Laravel.
