Installing php5-mysql

I’m new to using Local. A client of mine has an old website that I maintain, which I recently stopped being able to run on my local XAMPP when I upgraded from PHP 5.6 to 7, due to the use of the very old msql php functions removed deprecated in PHP 5.5 and removed from 7.0.

After installing Local and it seeming pretty great at first, I found that the deprecated mysql php api is not bundled and compiled by default. I’ve been looking through other support forums and trying to follow the guide at How do I compile additional PHP extensions?, but I cannot get this extension running. TBH, I think my main issue here is that the old mysql api is so ancient that I cannot find the correct package to download into my /app folder, but I am not sure.
