MySQL counter/hits script - Exclude my own IP

[chrisdee]

I have a mysql counter/hits script below that count all new ip adresses, but not the ones already counted. I would like to change it so that it count also all existing ip addresses except my own. Would greatly apreciate help on this.

<?php 
$username = "username"; 
$password = "password"; 
$host     = "localhost"; 
$database = "databasename"; 
$table      = "tablename"; 

mysql_connect($host,$username,$password) or die(mysql_error()); 
mysql_select_db($database) or die(mysql_error()); 

$ip=$_SERVER['REMOTE_ADDR']; 
$browser=$_SERVER['HTTP_USER_AGENT']; 
$date_now = date('Y.m.d - H:i:s'); 
$date_first = date('Y.m.d - H:i:s'); 

$ip_exists_check = "SELECT * from $table WHERE ip='$ip'"; 
$query=mysql_query($ip_exists_check); 
$check=mysql_fetch_assoc($query); 

if($check) { 
 $sql_update = "UPDATE $table SET date_now='$date_now' WHERE id='{$check[id]}'"; 
 $do_update = mysql_query($sql_update); 
} 

else { 
 $sql_insert = "INSERT INTO $table (browser,ip,date_now,date_first) 
 VALUES ('$browser','$ip','$date_now','$date_first')"; 
 $do_insert = mysql_query($sql_insert); 
} 
?>

<?php
// assuming your IP is 192.168.1.2
if($_SERVER['REMOTE_ADDR'] == '192.168.1.2') exit;
$username = "username";
$password = "password";
$host     = "localhost";
$database = "databasename";
$table      = "tablename";

mysql_connect($host,$username,$password) or die(mysql_error());
mysql_select_db($database) or die(mysql_error());

$ip=$_SERVER['REMOTE_ADDR'];
$browser=$_SERVER['HTTP_USER_AGENT'];
$date_now = date('Y.m.d - H:i:s');
$date_first = date('Y.m.d - H:i:s');

$ip_exists_check = "SELECT * from $table WHERE ip='$ip'";
$query=mysql_query($ip_exists_check);
$check=mysql_fetch_assoc($query);

if($check) {
$sql_update = "UPDATE $table SET date_now='$date_now' WHERE id='{$check[id]}'";
$do_update = mysql_query($sql_update);
}

else {
