You could be having problems with multiple users, if two visitors come
at the same time file locking problems come into play, one script could
unlink the file at the same time another script tries to open it
resulting in an empty file.
A database would be a better way to do this, but assuming you want to
stick with a text based counter instead of using rw and incrementing the
count you might consider opening the file in append mode and writing a
character to the file, then when you want to find out how many people
have visited count the lines in the file.
Using file based operations where you may have more than one user
operating on one file at the same time can get tricky so like I said
consider a database.
