Hehe, you've got a rather bad attitude toward this ;-) "wc -l" was my first thought, but even this isn't accessible on my managed host :-( And on Windows-Servers this won't be possible, too. Now I have several options, first: leave out maxLines. Second: use fopen/fgets to get the number of lines. Third: Get an approximate number by dividing the filesize with an average number (of characters in a line). I tried nr 3, it's of course fast, but unreliable. I then checked nr 2 and was positive surprise, it only took 0.001 secs for a logfile >10mb. Setting the size-limit to 1mb should reduce this amount farther. So I guess I'll stick with this method until someone has an idea for a better solution, without using system-calls.
