It'll be long. If your code does a lot of logging, it will be long, as it will have to log, and each line action it logs, will mean there's a line in your code. It shouldn't, however, be complicated in any case as logging is one of the most straightforward thing you can do.
What worries me, is that you mention "sometimes I even have to log in 2 tables". In my book, one, two, five, sixty or one thousand tables is performed by one line. Code is not doubled for each logger.
If you're copy-pasting a line, and changing $log to $log2 you're clearly doing it wrong (tm).
If you don't want to use any external tools you can write some sort of observer wrapper around debug_backtrace that loops through the backtrace and compares all function calls to an array map provided by the wrapper and if it's a hit, writes the respective log message with your custom message text. This would be a complete separation of code where you would just need to run this observer class at the end of every script.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
