    mysql_connect('localhost','root','') or die(mysql_error());
    mysql_select_db('new')  or die(mysql_error()); 
    $q=mysql_query('select * from stats where date IN (CURDATE())')  or die(mysql_error());
     mysql_query("insert into stats values(1,CURDATE())");
     mysql_query("update stats set view=view+1 where date IN (CURDATE())");

      - select * from stats where date IN (CURDATE()) is select the views if present in current date.
      - mysql_num_rows() return the number of rows selected. If it is 0, then value inserted into mysql table. Otherwise values are updated.

3. Stats(chart) using php and mysql:

                    Then you need to create statistics using php and mysql through google charts. There are many types of charts in google. You can choose anything as you want. The php code for create stats:


    mysql_connect('localhost','root','')  or die(mysql_error());
    mysql_select_db('new') or die(mysql_error());
    <script type="text/javascript" src=""></script>
    <script type="text/javascript">
      google.load("visualization", "1", {packages:["corechart"]});
      function drawChart() {var data = google.visualization.arrayToDataTable([
$str=" ['Day', 'Day'] ";
$query="select view as vi, DATE_FORMAT( date, '%b-%d' ) as dat from stats order by date ASC";
$result=mysql_query($query)  or die(mysql_error());
$str =$str . ",['". $rows['dat'] ."'," .$rows['vi'] ."]" ;
echo $str;

      var options = {
          //title: 'Company Performance',
          hAxis: {title: 'Day', titleTextStyle: {color: 'red'}},
          vAxis: {title: 'Total views', titleTextStyle: {color: '#FF0000'}, maxValue:'5', minValue:'1'},

        var chart = new google.visualization.ColumnChart(document.getElementById('chart_div'));
        chart.draw(data, options);
   <p style="font-size:20px;">Dialy Stats</p>
   <div id="chart_div" style="width: 400px; height: 200px;"></div>

               The following MySQL query is used to find total number of views of your websites per daily
        - select view as vi, DATE_FORMAT( date, '%b-%d' ) as dat from stats order by date ASC
is select the number of views daily.
