Print newline with single quotes in PHP

Question

I tried to use single quotes as much as possible, but I noticed that I can't use n inside single quotes. I know I could enter the newline character directly by pressing enter, but that would break the indentation of my code.

When I use single quotes, is there some ASCII character or something I can type that will produce a newline?

Answer 1

echo 'hollow world' . PHP_EOL;

Use the constant PHP_EOL then it is also operating system independent.

Answer 2

No, because single quotes suppress even hex code replacement.

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