* PHP8.3 compatibility

Turns out PHP<8.3's proc_open does not really care if the requested working_dir does not exist, while PHP>=8.3's proc_open bails if it does not exist.

And due to a typo in the code, the dir never existed.

And due to insufficient error checking, the error was not really detected.

Took fking 4 hours to track down, and the fix is 1 byte. divinity76#1

Should probably complain to the php-src bugtracker, i am guessing the proc_open behavior change was unintentional

* StyleCI

strftime was deprecated in PHP8.1.0.
This is the only PHP8.3.0 compatibility issue detected by the PHPCompatibility scanner git version right now:
