you can slip by a linebreak, but you will have to make sure what the
linebreak look like. Since different applications and operating systems
code a linebreak in different ways it is probably a good idea to have a
preg_replace inside the split, converting all linebreaks that might occur
to the one you split by.

First of all, split takes a string and an array so you should quote
the line break:
split("\n", $arr);

Unix has \n linebreaks, Windows has \r\n and Mac may have \r
linebreaks.

split("\n", $arr) works on both Unix and Windows, but in Windows the
array will still contain \r at the end.

Something like this will work with \n, \r, \r\n and \n\r:
$lines = preg_split("^[\r\n]+^", $contents);

I see now that I misunderstood your question. So my previous post is a
fine answer, but not to your question.

Thanks.
