I do micro optimization with every language I use, when I know, and where I can. I am the one that usually solves slow query problems, and I use best practices on database as well. Guys, I don't get your point ... if you know that "$var" is a non-sense, feel free to use it ... what I know, is that every double quoted string require parsing, due to variable or char evaluations (\x00) evaluation, if I don't need this waste of time, why should I write a totally meaningless, useless, "$var" where $var is sufficient or more over 'whatever'.$var will be faster? The fact is that this is my approach for every layer of an application, I am not like that only with PHP. There is something to optimize? Make it your code style and you won't spend a sinlge second more than any other, but at least you'll do your best to reach best performances. As I have said, I have never had performances problem, and I am a full web stack developer, but you can obviously do whatever you want, is still a matter of points of view.
