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?

I found PHP_EOL very useful for file handling, specially if you are writing multiple lines of content into a file.

For example, you have a long string that you want to break into the multiple lines while writing into plain file. Using \r\n might not work so simply put PHP_EOL into your script and the result is awesome.
