How do I run PHP code when a user clicks on a link?

I have an image .

<image name="" src="">

I have a php code that needs to be run only after the image has been clicked.

<?php

$var = somthing;
if(condition)
{
    sql stmts;
}

?>

like that.

Both are in the same php page. PLease help me to sort out this problem.

Thanks..

Please learn at least elementary basics about technologies you are trying to use first. The keyword you missed here is "server side". — Marcin Orlowski, Oct 03 '12 at 12:06
PHP is server side and javascript, if you want to run SQL after clicking an image you need an AJAX request — EaterOfCode, Oct 03 '12 at 12:07
Wrap the image in a link and call the page with an additional GET parameter to decide whether or not to execute the statements. — Louis Huppenbauer, Oct 03 '12 at 12:07
Php runs in the server, javascript runs in the browser. You sound like you have a situation than requires the use of Ajax (In which a javascript event can request data from a php page) — enhzflep, Oct 03 '12 at 12:07
Please before you start to programme in some environment, in your case in web, learn how things work first. You'll save nights of solving some basic questions. — Zaffy, Oct 03 '12 at 12:10

You can send a request with javascript. With jQuery that would look like this:

$.get("yourfile.php?function=imageClick", function(data){});

In your php somewhere at the top add:

if($_GET['function'] == 'imageClick'){
  // do your php stuff
}

You can't run PHP code on the client side.
