Debugging addons \ modules \ hooks experience

[Gricenko Mihail]

Hello guys. Just simple question. What kind of configuration for environment do you use to write \ debug code of your addons \ modules \ hooks? Have you use any debuggers or just. I have asked question early 

 and wondering... nobody use IDE with debugger to write they code? how it's possible? how do you write complex addons or modules with lot of logic? please explain me this thing, i have stuck with latest version of WHMCS and very large custom module, description of my issue is on the link above

Thanks
