How to Install Composer in Windows 11

Composer is one of those tools you’ll find yourself using all the time if you work with PHP. It’s a dependency manager that helps you install, update, and manage libraries seamlessly—no more manually downloading files or copying folders.

If you’re running Windows 11 and want to set up Composer to handle your PHP projects efficiently, you’re in the right place. In this guide, we’ll walk you through every step, from installation to verification.

What You’ll Need Before Installing Composer

Before diving in, make sure you have the following ready:

• PHP installed on your system (preferably PHP 8.0 or newer).
• Windows 11 with administrator privileges.
• An active internet connection (Composer downloads dependencies online).

If you haven’t installed PHP yet, grab the latest version from Windows PHP downloads. Once done, make sure the PHP path is added to your system environment variables.

Step 1: Download the Composer Installer

The easiest way to install Composer on Windows is through its official installer.

1. Visit the official Composer website: https://getcomposer.org/download/
2. Scroll down and click “Composer-Setup.exe” to download the Windows installer.
3. Once downloaded, double-click the .exe file to begin installation.

The setup wizard will guide you through the process—don’t worry, it’s very straightforward.

Step 2: Configure PHP for Composer

During installation, Composer will ask where your PHP executable is located.
By default, it should be in a directory like:

C:\xampp\php\php.exe

or

C:\Program Files\php\php.exe

If you’re using XAMPP or WAMP, select the PHP path from their respective installation folders.

Tip: If the installer can’t find PHP automatically, you can manually browse to the PHP folder and select php.exe

Step 3: Complete the Installation

Once the PHP path is set, the setup wizard will ask if you want to install Composer globally.
Make sure to check “Add Composer to the PATH” — this ensures you can run it from any command prompt window.

Now click Next and let the installer finish. Composer will download the required components and finalize the setup.

Step 4: Verify Composer Installation

After installation, let’s confirm that everything is working properly.

1. Open Command Prompt (CMD) or Windows Terminal.
2. Type the following command:

composer -V

or

composer --version

If the installation was successful, you’ll see something like this:

Composer version 2.7.6 2025-11-01 10:32:45

That’s it—Composer is now installed globally and ready to use!

Step 5: Test Composer With a Project

Let’s make sure Composer actually works with a PHP project.

1. Create a new folder, for example: C:\Users\YourName\Projects\test-composer
2. Open that folder in CMD and run: composer init
3. Follow the prompts to create a composer.json file.
4. Now, install a test package like monolog by running: composer require monolog/monolog

Composer will download and install the package, and you’ll see a new vendor folder appear—confirmation that everything is working perfectly.

Wrapping Up

And that’s how you install Composer in Windows 11! Once set up, you’ll be able to manage PHP dependencies effortlessly—no more manual file juggling.

Whether you’re building Laravel apps, WordPress plugins, or custom frameworks, Composer will keep your environment clean, modular, and easy to maintain.

If you ever switch machines or reinstall Windows, just repeat this setup and you’ll be back in action in no time.
