eol - 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?

Answer 1

Yes, PHP_EOL is ostensibly used to find the newline character in a cross-platform-compatible way, so it handles DOS/Unix issues.

Note that PHP_EOL represents the endline character for the current system. For instance, it will not find a Windows endline when executed on a unix-like system.
