What is Composer?
Composer is a dependency manager for PHP. It allows you to declare the libraries your project depends on and it will manage (install/update) them for you. It’s a powerful tool that simplifies the process of managing dependencies in PHP projects.
Why Install Composer on Ubuntu?
Installing Composer on Ubuntu gives you access to a powerful dependency management tool for PHP. It allows you to easily manage dependencies for your PHP projects, making it easier to maintain and update your codebase. Whether you are working on a small personal project or a large enterprise application, Composer can help you manage your project’s dependencies efficiently.
Installing Composer on Ubuntu
Installing Composer on Ubuntu is a straightforward process. In this tutorial, we will walk you through the steps to install Composer on Ubuntu.
Step 1: Update Package Lists
Before installing any new software, it’s always a good idea to update the package lists to ensure you are installing the latest versions of the software. You can do this by running the following command:
$ sudo apt update
Step 2: Install Curl and PHP
Composer requires Curl and PHP to be installed on your system. If you don’t have Curl and PHP installed, you can install them using the following command:
$ sudo apt install curl php-cli php-mbstring git unzip
Step 3: Download Composer
Once you have Curl and PHP installed, you can download the Composer installer using the following command:
$ curl -sS https://getcomposer.org/installer -o composer-setup.php
Step 4: Verify the Installer
Before running the installer, it’s important to verify the integrity of the installer. You can do this by downloading the signature of the installer and verifying it using the following commands:
$ curl -sS https://composer.github.io/installer.sig -o composer-setup.sig
$ sha384sum composer-setup.php
The output of the second command should match the content of the composer-setup.sig file. If the output matches, you can proceed to the next step.
Step 5: Install Composer
To install Composer, you can run the following command:
$ php composer-setup.php --install-dir=/usr/local/bin --filename=composer
This command will install Composer globally on your system, making it accessible from any directory.
Step 6: Verify the Installation
To verify that Composer has been installed successfully, you can run the following command:
$ composer --version
If the installation was successful, you should see the version of Composer printed to the console.
