Answer 1

if (file_exists('count_file.txt')) 
    {
    $fil = fopen('count_file.txt', r);
    $dat = fread($fil, filesize('count_file.txt')); 
    echo $dat+1;
    fclose($fil);
    $fil = fopen('count_file.txt', w);
    fwrite($fil, $dat+1);
    }

    else
    {
    $fil = fopen('count_file.txt', w);
    fwrite($fil, 1);
    echo '1';
fclose($fil);
}
?>

For any "decent" counter I would recommend to use a database (mysql, redis ) and trace IP address to have even deeper analytics (e.g how many unique visits, where they are comming from etc)
