How do I install Composer PHP packages without Composer?

An alternative solution that worked for me (since php-download was down) can be done by making your own little local composer downloader.

1. Download and install XAMPP locally: https://www.apachefriends.org/index.html
2. Download and install composer locally: https://getcomposer.org/download/
3. Open commandprompt, navigate to say c:\temp and and simply type the composer dependancy, for example: composer require league/oauth2-client
4. Copy the files from your c:\temp folder to your web host using an FTP program
5. Add this to the top of your php: require("vendor/autoload.php");
