string - Print newline in PHP in single quotes

Question

I try to use single quotes as much as possible and I've noticed that I can't use in single quotes. I know I can just enter a newline literally by pressing return, but that screws up the indentation of my code.

Is there some ASCII character or something that I can type that will produce newline when I'm using single quotes?

Answer 1

No, because single-quotes even inhibit hex code replacement.

echo 'Hello, world!' . "xA";
