The part that you're missing here is that it's not your data structures
that may be invalid, it's engine's. And what you call "I can save and
quit", the engine calls "execute arbitrary amount of code", for which it
needs valid data structures. Unless your "save and quit" code does not
call any functions and does nothing useful at all, from the engine POV
your "save and quit" is no different from "continue working normally" -
it needs all the data structures to be in a perfect order as if nothing
bad happened. For some errors, it may be possible. For some, it may be
possible but hard. For some, it may not be possible. But the main point
here is this:
For the engine, there's no difference between "continue normally as
nothing happened" and "save and quit", as soon as you start running PHP
code that does anything useful at all.
So if you can recover from an error, you can recover to a normal state.
If you can not, then you can not. There's no "save and quit" scenario
here that can do anything different.
