How do I add PHPadmin to my bootstrap.sh commands? - vagrant-provision

Question

I've been away from PHP nearly four years, I've been working in javascript and Node.JS instead. I have a memory of what tools I was comfortable working with.. it's a rusty memory how it all went together. I've followed Traversy's tutorial to get the LAMP box running
and have connected from MySQL WorkBench.
I'd like to use PHPAdmin, How do I add PHPadmin to my bootstrap.sh commands?
Installing phpMyAdmin On Vagrant
I like this version best, cause each domain has it's own /phpadmin, but I don't understand how he is editing the config file from inside bootstrap.sh
A super-simple Vagrant LAMP stack bootstrap (installable with one command)
I tried this one first, but got an error from the first curly brace, saying it didn't recognize the character..
bootstrap.sh
