PHP Composer is a dependency manager for PHP, enabling you to manage libraries and packages for your PHP projects efficiently. In this guide, we will walk through the steps to install and use PHP Composer on AlmaLinux 8.
Step 1: Update Your System
Start by ensuring your system is up to date:
sudo dnf update -yStep 2: Install PHP and Required Extensions
Before installing Composer, you need to have PHP and some required extensions installed. You can install PHP by running:
sudo dnf install -y php php-cli php-mbstring unzipStep 3: Download Composer Installer
Download the Composer installer using PHP:
php -r "copy('https://getcomposer.org/installer', 'composer-setup.php');"Step 4: Verify the Installer
It is good practice to verify the installer to ensure its integrity. You can do this by comparing the SHA-384 hash:
php -r "if (hash_file('sha384', 'composer-setup.php') === '2e9b0e5...') { echo 'Installer verified'; } else { echo 'Installer corrupt'; unlink('composer-setup.php'); } echo PHP_EOL;"Make sure to replace 2e9b0e5... with the latest hash from the Composer website.
Step 5: Install Composer
Once verified, run the installer:
php composer-setup.php --install-dir=/usr/local/bin --filename=composerStep 6: Verify Composer Installation
To confirm that Composer was installed successfully, run:
composer --versionYou should see the version of Composer displayed.
Step 7: Using Composer
Now that Composer is installed, you can use it to manage your PHP project dependencies. To create a new project, navigate to your project directory and run:
composer create-project --prefer-dist laravel/laravel my-laravel-appStep 8: Update Composer (Optional)
To ensure you have the latest version of Composer, you can update it using:
composer self-updateConclusion
