Say your implementation uses some global variable called $history. Now 
say I type "$history = [];" at the interactive prompt. Won't that break it?

Not global variables but class attributes.

Of course not. We read chars one by one on stdin. If a mapping is 
detected, then we call the associated callable. The line is never 
executing/evaluating as a PHP code (except if this is what you want 
obviously).

Cheers :-).

Eh? I thought PHP interactive evaluated the code? What's the use of only 
being able to use functions?

The code I presented only replace the readline functionnality (like 
Linenoise does). Then you can evaluate the code with the help of a 
temporary file, FastCGI & co., I don't know ;-).

Best regards :-).
