Installing PHP 7 and Composer on Windows 10, Natively | Jeff Geerling

Note: If you want to install and use PHP 7 and Composer within the Windows Subsystem for Linux (WSL) using Ubuntu, I wrote a guide for that, too! I am working a lot on Composer-based Drupal projects lately (especially gearing up for DrupalCon Nashville and my joint workshop on Drupal and Composer with Matthew Grasmick), and have been trying to come up with the simplest solutions that work across macOS, Linux, and Windows. For macOS and Linux, getting PHP and Composer installed is fairly quick and easy. However, on Windows there seem to crop up little issues here and there.
