How to Install Composer on Ubuntu 22.04

Hey there! If you're diving into the world of PHP development on your Ubuntu 22.04 machine, you'll likely come across Composer—a nifty tool for managing packages and dependencies. Let me walk you through the steps of getting Composer up and running on your system.

So, let's see how to install composer on ubuntu 22.04, ubuntu 22.04 install composer, composer install ubuntu, composer install laravel 8/9/10.

Press Ctrl + Alt + T to open a terminal window. This is where we'll enter the commands.

Before installing any new software, it's a good practice to update the package lists. Type the following command and press Enter

sudo apt update

Composer requires some dependencies to work properly. Install them by running:

sudo apt install curl php-cli php-mbstring unzip

Now, let's download the Composer installer using curl. Run the following command.

curl -sS https://getcomposer.org/installer -o composer-setup.php

To ensure the integrity of the installer, you can verify it with the expected SHA-384 hash. Run these commands.

HASH=$(curl -sS https://composer.github.io/installer.sig)
php -r "if (hash_file('sha384', 'composer-setup.php') === '$HASH') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"

Now, let's install Composer globally on your system:

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

After the installation is complete, you can remove the downloaded setup file:

rm composer-setup.php

To verify that Composer is installed successfully, run:

composer --version

If you see the Composer version information, congratulations! You have successfully installed Composer on Ubuntu 22.04.

That's it! You can now use Composer to manage PHP packages and dependencies on your Ubuntu system.
