How to Install Composer Globally in 2025?

Composer remains an essential tool for PHP developers, automating dependency management and ensuring seamless project integration. Here’s a straightforward guide on how to install Composer globally on your system in 2025.

Step-by-Step Installation Guide

1. Preparation: Ensure you have PHP installed. You can verify this by running php -v in your terminal.

2. Download Composer Installer: Utilize the following command to download the Composer installer in a secure manner:

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

3. Verify Installer Integrity: It’s imperative to verify the installer’s SHA-384 to guarantee its integrity. You can find the latest expected hash on the Composer Public Keys / Signatures page.

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

4. Run the Installer: Once verified, execute the installer using:

   1	php composer-setup.php

5. Remove the Installer: Clean up by deleting the setup file:

   1	php -r "unlink('composer-setup.php');"

6. Move Composer Globally: To make Composer globally accessible, move it to a directory within your system’s PATH:

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

7. Verify Installation: Ensure Composer is installed successfully by checking the version:

   1	composer --version
