Download & Install Composer: Step-by-Step Guide

Introduction

Welcome to our step-by-step guide on downloading Composer! In this article, we’ll walk you through the process of acquiring and setting up Composer, a powerful dependency management tool for PHP. Whether you’re a seasoned developer or just starting out, this guide will help you get Composer up and running smoothly.

What is Composer?

Composer is a dependency manager for PHP that simplifies the process of integrating third-party libraries and packages into your projects. It allows you to specify the libraries your project depends on and will manage (install/update) them for you.

Why Use Composer?

Using Composer streamlines the development process by automating the retrieval of required libraries and ensuring version compatibility. This reduces the time spent on manual setup and minimizes the risk of compatibility issues between different packages.

Step to Download Composer

Step 1

First go to composer website, which you can visit by CLICKING HERE.

Step 2

After visiting composer website. Now click to DOWNLOAD option as mentioned below.

Step 3 (For LINUX OPERATING SYSTEM)

After clicking on DOWNLOAD. Open up your system Terminal. Run the below commands.

php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"
php -r "if (hash_file('sha384', 'composer-setup.php') === 'e21205b207c3ff031906575712edab6f13eb0b361f2085f1f1237b7126d785e826a450292b6cfd1d64d92e6563bbde02') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"
php composer-setup.php
php -r "unlink('composer-setup.php');"

This installer script will simply check some php.ini settings, warn you if they are set incorrectly, and then download the latest composer.phar in the current directory. The 4 lines above will, in order:

• Download the installer to the current directory
• Verify the installer SHA-384, which you can also cross-check here
• Run the installer
• Remove the installer

Step 4

To access the composer globally, you need to move composer.phar into directory in your PATH for instance:

sudo mv composer.phar /usr/local/bin/composer

For details, see the instructions on how to install Composer globally.

Step 3 (For WINDOWS OPERATING SYSTEM)

This is the simplest method for installing Composer on your computer.

Start Composer-Setup.exe by downloading it. The most recent Composer version will be installed, and your PATH will be configured so that you can run Composer from any directory on your command line.

NOTE: Shut down the current terminal. Use a fresh terminal to test usage: This is significant since the PATH is only loaded during terminal startup.

Now, you learn how to download and install the COMPOSER to locally or globally. Same steps will work on production server as well.
