It's very simple - at the top of every page, have a routine that opens a
text file, reads the number inside it into a variable, adds one, and writes
it back out again. If the text file doesn't exist, create it.
Psuedocode:
if (file exists) {
open file for reading;
read contents into $counter;
increase $counter by 1;
} else {
set $counter to 1;
open file for writing;
}
write $counter to file;
close file;
print "you are visitor number $counter.";
Look into fopen(), fread(), fwrite() and friends. Of course, it's now up to
you to work out how you're going to count cached requests, search engine
bots, link checkers, etc etc. Personally I reckon you're better off with
this:
<?php
mt_srand((double)microtime()*1000000);
$counter = mt_rand(1, 999999999);
echo "You are visitor number $counter.";
?>
Cheers
