Re: [PHP] Website Hit counter and Logger
One not, Amos, is that instead of using $count += 1, you should just do
$count++. That will automatically increment the number.

You can probably find binaries for both, or download logfiles and run

Wait...
You CREATE logfiles from PHP as if they were Apache logfiles, and run
them through Webalizer?...
Surely the host provides access to log files, no?...

Way off low, or way off high?

Seems to me you need another flock($fp, 2) here to get exclusive write
access to the file...
Otherwise, you haven't avoided the race condition at all, you've just
added a bunch of flock calls that don't do much of anything...

Webalizer works fine, and the output is good (though I doubt it's as
accurate since it's tied into the hit counter). That part of the script
is fully functional.

Yes, the host provides access to log files for domains and virtual
hosts. The logs I create are for specific subdirectories where the
sites reside.
Believe me, if I was in charge of how this was run, each customer would
have a virtual host of their own and creating the logs wouldn't need to
happen. As it is, I have to maintain two versions of the script. One
for the site-in-a-directory situation, and the other for virtual hosts
that uses server logs.
My dilemma is that the hit counter portion of the script works at
first,
then at some point loses track, and displays a number that is way off
from the actual number.

Way off low. I assume something causing the number to be reset to zero
at some point.
I was originally using code that read the number from a text file,
added
1 to it, then wrote it back using file_get/put_contents.
Since then I have changed to
if (file_exists($logfile)) {
$fp = fopen($logfile, r+);

fseek($fp,0);

access to the file...
Thanks, I'll give that a try.
I had a hunch that it might have been happening when two people visit at
once and the server just gives up on who gets write access to the file,
but I haven't had much time to familiarize myself with file locking.
Otherwise, you haven't avoided the race condition at all, you've just

fputs($fp, $count);
flock($fp, 3);

Re: [PHP] Website Hit counter and Logger
Thanks Daniel, I will switch that. Like I said, I copied it from
someone's (obviously erroneous) example and didn't want to mess it
up... I usually use variable++ for increments.

Re: [PHP] Website Hit counter and Logger
Here's an idea for testing purposes to determine why it's counting low,
too
Have your PHP script write to two files --- one that contains the number
as it is now, and one that writes the number and a timestamp on a new line
each time it's accessed. This way, you can scan down the list to see where
the error occurs, and then cross-check it with your Apache logs at the time
indicated by the timestamp.
