Question about Julie Meloni tutorial

I'm working on the Hotwired "Authenticate and Track Users with PHP" tutorial here: http://hotwired.lycos.com/webmonkey/00/05/index2a_page3.html?tw=programming I have a file with user:passwd pairs in it like this: user:pass user:pass user:pass Three lines only. There definitely isn't a trailing \n at the end. I'm absolutely sure, after checking 100 times. When I do this: $filename = "bla/bla/bla/accounts.txt"; $fp = fopen($filename, "r"); $file_contents = fread($fp, filesize($filename)); fclose($fp); $line = explode("\n", $file_contents); echo sizeof($line); ...I get 4 instead of 3. $line[3] is empty but it's there. Where is it coming from? Why do I have to use (sizeof($line)-1) to get the right count? I using BBEdit on MacOS, saving as UNIX text. But the same thing happens if I create accounts.txt with vim or gedit on the Linux server. If I replace the file reading stuff with $file_contents="user:pass user:pass user:pass"; I don't have the problem.
