Hi, how can i make a link add 1 to a field in my database??

In my db table i have 4 fields. ID, Link, Description and "number of clicks". How can I make "number of clicks" increase by 1 when i press on a link? Each link is printed from the Link field.

PHP Code:
        echo "<tr>";
 
        echo "<td class=tabell><img src=$row[2].jpg></td>";
        echo "<td class=tabell>".$row[1]."<br><font color=red size=2>Antal klick: $row[3]</font></td>";
        echo "<td class=tabell>".$row[0]."</td>";
        echo "</tr>"; 
$row[1] contains the whole link <a href....> in the db table and $row[3] (number of clicks) only shows "0" because I can't get it to increase when i click on the link.

Or maybe this is totally wrong. Maybe i should build it all in another way?
