upgrade-php7.sh

#!/usr/bin/env bash
# Upgrade an Amazon Linux EC2 to PHP 7.3
#
# Last tested w/ PHP 7.2 AWS Linux version 2.8.5
#
# Must be ran as sudo:
#     sudo bash upgrade-php7.sh
#
# Can be added to ./.ebextensions/20_php.config like so:
#  container_commands:

#      command: sudo bash scripts/upgrade-php7.sh

# We will remove instances of PHP matching:
