How to set hit counter in yii - php

Question

I'd like to make a hit counter that will add the count when user enter the website through their ip address. This is my code:
for views:
<?php echo number_format(Visitor::model()->GetAll('portal')); ?>
this is my model:
public function attributeLabels() {
return array(
'id' => 'ID',
'web' => 'Web',
'dtvisit' => 'Dtvisit',
'total' => 'Total',
);
}
public function AddVisitor($web) {
date_default_timezone_set('Asia/Kuala_Lumpur');
$today = date('Y-m-d');
$model = $this->findByAttributes(array('dtvisit' => $today, 'web' => $web));
if (sizeof($model) > 0) {
//update
$model2 = $this->findByPk($model->id);
$model2->total = (1 + $model->total);
$model2->save();
} else {
//add new
$model2 = new Visitor;
$model2->web = $web;
$model2->dtvisit = $today;
$model2->total = 1;
$model2->save();
}
}
public function GetAll($web) {
date_default_timezone_set('Asia/Kuala_Lumpur');
$model = $this->findAll(array("condition" => "web='$web'"));
$total = 0;
if (sizeof($model) > 0) {
foreach ($model as $row) {
$total+= (int) $row->total;
}
}
return $total;
}
CUrrently, the total will add everytime I refresh or click any links on my website. How to make it add the total only when new user enter the website. Thank you

I think you should use Params for passing value
public function GetAll($web) {
date_default_timezone_set('Asia/Kuala_Lumpur');
$model = $this->findAll(array("condition" => "web=':web'",
'params' => array(:web=$web)));
$total = 0;
if (sizeof($model) > 0) {
foreach ($model as $row) {
$total+= (int) $row->total;
}
}
return $total;
}
