<?
//counter.php
//check and read file data.txt
if(file_exists("data.txt"))
{
$PF=fopen("data.txt",'r');
$num=fgets($PF,4096);
fclose($SP);
//add value to $num
$num++;
$PF=fopen("data.txt",'w');
fputs($PF,$num);
fclose($PF);
chop($num);
$nb_digits=max(strlen($num),6);
$num=substr("0000000000".$num,-$nb_digits);
//show on page
echo "You are $num"."th"." visitor";
}else
