> if the team is familiar with 2003 vintage PHP, you should meet them there. That's still a thing you can write a website in.

You can write a website in it, but you cannot test it for shit.

If this is true, OP can consider writing tests of the website using a frontend test suite like Cypress, especially with access to local instances connected to local databases.

There's no value to retroactive unit testing. Retroactive tests should be end-to-end or integration level, which you certainly can do without a framework.

Framework are not needed to test. I've been testing and validating my code way back, in C. Not because I was an early adopter (I'm still not), but because I needed to debug it, so... faster.
