Of course there are many more ways of doing it. To tell you the harsh truth: (I hope you can handle it ;) ) Loading a file into an array and using array shifting and than write that array into a file and that for every (!) log action - that is surely one of the worst. ;) I have two other ways for you: 1) if filesize of logfile exceeds 20k use fseek() to jump to position filesize()-10k and write the rest into a new file. delete old log and rename new file to log file name. This is the fastest. I cut down to 10k so you do not have to do it too often. If you want it a bit nicer you can start copying after finding a \n for the first time. But most times you only look at the tail - so nobody cares. Another way is cycling files: 2) If log reaches 10k rename it and start a new file with that name. "rejected.log" and "rejected.older.log" can be of use. ;) THe first is closer to what you tried but the second is far more performant.
