In addition of all people said, I would add a lock to the file :
>$cf = fopen($counter_file,"w");
flock($cf,LOCK_EX);
>fputs($cf, "$counter_file_line[0]");
>fclose($cf);
This to avoid another script attempt to read the file while you update it...
I had the problem, so sometimes the counter return to zero...
