When do I use the PHP constant “PHP_EOL”?

Question

When is it a good idea to use PHP_EOL?

I sometimes see this in code samples of PHP. Does this handle DOS/Mac/Unix endline issues?

Handy with error_log() if you're outputting multiple lines.

I've found a lot of debug statements look weird on my windows install since the developers have assumed unix endings when breaking up strings.
