PHP hit counter

Penasaran sama cara kerja hit counter membuat gue mencari-cari tutorial kesana kemari
Dan akhirnya...
Taraaaaa
This is it...

Langkah pertama buat dulu database nya dengan nama hitcounter, setelah itu buat tabelnya, bisa langsung menggunakan phpMyAdmin bisa juga dengan coding.
CREATE TABLE `visitor` (
`counter` int(9) NOT NULL default '0'
) TYPE=MyISAM;

Langkah kedua buat script counter.php
<?php
$host="localhost"; // Host name
$username="root"; // Mysql username
$password=""; // Mysql password
$db_name="hitcounter"; // Database name
$tbl_name="visitor"; // Table name

// Connect to server and select database.
mysql_connect("$host", "$username", "$password")or die("cannot connect to server ");
mysql_select_db("$db_name")or die("cannot select DB");
$sql = "SELECT * FROM $tbl_name";
$result = mysql_query($sql);

$rows = mysql_fetch_array($result);
$counter = $rows['counter'];

// if have no counter value set counter = 1
if(empty($counter)){
$counter = 1;
$sql1 = "INSERT INTO $tbl_name(counter) VALUES('$counter')";
$result1 = mysql_query($sql1);
}

echo "You 're visitors No. ";
echo "<b>".$counter."</b>";

// count more value
$addcounter = $counter + 1;
$sql2 = "update $tbl_name set counter = '$addcounter'";
$result2 = mysql_query($sql2);

mysql_close();
?>
