Lets say i have the text [1] and i whant it to change a variable when clicked on. so variable $i would be changed from 1 to 2. How do i do this?

If you want it to happen without leaving the page, javascript.

You could also possibly use $_GET.

 

Link:

<a href="yourpage.php?changevar=true">Change the variable!</a>

 

Code on yourpage.php:

$i = 1;
if ($_GET['changevar'] == true) {
   $i = 2;
   // Other actions...
}
