In this guide, I’ll be showing you step-by-step what you need to do to install the Windows Subsystem for Linux, and then both PHP and the Composer package manager.
As a prerequisite, this requires an up-to-date version of Windows 10. Windows 8.1, 7, and below are unsupported. I will write about setting up PHP environments under legacy Windows versions in a later article.
Step One – Installing WSL
First, use your start menu or Cortana search bar to search for “windows features” – the first option provided will be a tool to add or remove features to your Windows installation. Select this.
Once the dialogue appears, scroll down until you can find Windows Subsystem for Linux. Tick the box and click OK. Windows will download and install this functionality, and may require a system restart afterwards.
Step Two – Installing a Linux distribution
After a restart, we can now choose a Linux distribution. Open the Microsoft Store app that you can find in your start menu. On the app, search for linux to bring up a list of available distributions.
You’re free to choose whatever distribution I want, but for a beginner, it’s my personal recommendation that you install Ubuntu as it’s well supported, easy-to-use, and does not require any complex configuration. Click on the one you want, and choose either Get or Install – depending on your system’s locale. Once it’s downloaded, the button’s text should change to Launch and Ubuntu will appear in your start menu. Fire it up.
Step Three – Installation and UNIX username
After opening the app, it will take a few minutes to install. This can take a while on older systems, but fret not, it will finish!
After a short while, it will prompt you to set a UNIX username. This should be a single word, all lowercase, with no spaces or symbols. My name is Oliver, so oliver is fine. Then set a password. This does not need to be the same as the password you use to log in to Windows. Don’t forget, your password won’t actually appear as asterisks as you type it, but it’s definitely there – it’s normal on these platforms.
Once that’s done, you’ll be presented with a command line and information regarding the system information.
Step Four – Installation of PHP
Before you install PHP, you might need to refresh Ubuntu’s repositories. I know this sounds complicated, but think of it like Ubuntu checking an app store for what’s available. Type the following command to do this:
sudo apt update
It might prompt you that there are updates available, but you can take care of that later. Once update is done, we can install PHP. Type the following command:
sudo apt install php
Sudo (short for superuser do) allows you to run commands as an administrator (root) – which is necessary for installing new software. Apt is Ubuntu’s package manager – necessary for pulling in said software. It will prompt you for the password you set earlier.
The package manger may be different if you installed a different Linux distribution. openSUSE for example uses Zypper instead.
Give the package manager some time to install and configure PHP and all of its prerequisites. Once it’s done, you can check that it’s fully installed using the following command:
This should print PHP’s version to the screen. As of this time of writing, Ubuntu installs PHP 7.4 by default. My output looks like this:
PHP 7.4.3 (cli) (built: May 26 2020 12:24:22) ( NTS ) Copyright (c) The PHP Group Zend Engine v3.4.0, Copyright (c) Zend Technologies with Zend OPcache v7.4.3, Copyright (c), by Zend Technologies
PHP’s package manager is called Composer, and this can be easily installed at the command line in the same way you did PHP:
sudo apt install composer
Similarly, you can check the version and status of Composer using
Your output will look similar to mine, along with a long list of commands and some ASCII art:
Composer 1.10.1 2020-03-13 20:34:27
Now Composer will be available at the command line for you to install global packages with, or to install local dependencies outlined in a project’s
Optional: Update Linux
As previously mentioned, you should update your Linux installation from time to time. You can do this by running the following command:
sudo apt update && sudo apt upgrade
This double command will ensure that Ubuntu has the most up-to-date list of software, and then upgrade your software to the latest versions.
Optional: Install the Laravel installer and add Composer binaries to PATH
First, install the Laravel installer using Composer:
composer global require laravel/installer
After this is installed, you should normally be able to type
laravel to access its installer, but you should get an error. Why?
By default, any software you install globally via Composer won’t be instantly accessible from your command line, because Composer’s directories have not been added to your PATH. If you’re not sure what this is, don’t worry – in a nutshell, this is information that tells your terminal where it can find the programs that you type in (like
php) so they can be ran. Windows has this too.
To fix this, you need to open your aliases file in a text editor. We’ll use Nano, but feel free to use something else:
In this file, type:
Press CTRL+O to save, and CTRL+X to close Nano. With this change in place, we need to reload Bash’s configuration. You only need to do this once.
Now, your Composer global applications will work. Type
laravel to confirm this.
By following this guide, you should be able to install the WSL under Windows 10 with Ubuntu, and have a functioning installation of PHP and Composer ready to go. I hope that this helps.
