Purpose: 
This function will enable the user to put a counter on there website that
requires no database. You must pass (1) variable with this function and that
variable would be the filename of the text file to write the counter number
to. (ie. text/counter.txt) This folder and file must be set so it can be written
to. Set this folder to '666' in the CHMOD. To make the file, you can just
open notepad and save a blank .txt file to the folder you wish to house the
counter text file. Just remember to leave the text file blank to start at 0, or
you can type a number to start at that number. For instance, to start at
5011, you would type 5011 in the text file and save the file. You must also
make sure there are no extra lines (carriage returns) in the text file. To
check this just try to place you cursor under the first line with your mouse,
click under the line and if the cursor just shows up after the first line, you
are ready to go, if not, then delete the extra lines.

Example:
$path = "counter.txt";
print 'This page has been accessed ('.CallCounter($path).') times.';
