how can i force a linebreak in a txt database?

Question

I'm working with PHP, and I would like to create a line-break in my .txt database after every input. Is this even possible and how? Please help, I have tried /n and <br> but these won't work. Some code:

fwrite($handle,$artikelnummer);
fwrite($handle,$newData);

Between these two I want a linebreak

Answer 1

Something like this?

fwrite($handle, $artikelnummer);
fwrite($handle, "\n");
fwrite($handle, $newData);

As Shikhar Bhardwaj pointed out, you could use PHP_EOL, instead of "\n", if you want to be completely OS platform independent...

UPDATE: If what you expect is one empty line between lines, you have to write 2 newlines...:

fwrite($handle, $artikelnummer);
fwrite($handle, PHP_EOL . PHP_EOL);
fwrite($handle, $newData);
