HREF to call a PHP function and pass a variable?

Question

Is it possible to create an HREF link that calls a PHP function and passes a variable along with it?

<?php
function sample(){
    foreach ($json_output->object ){
        $name = "{$object->title}";
        $id = "{$object->id}";

        print "<a href='search($id)' >$name</a>";
    }
}

function search($id){
    //run a search via the id provide by the clicking of that particular name link
}
?>

You can do this easily without using a framework. By default, anything that comes after a ? in a URL is a GET variable.

So for example, www.google.com/search.html?term=blah

Would go to www.google.com/search.html, and would pass the GET variable "term" with the value "blah".

Multiple variables can be separated with a &

So for example, www.google.com/search.html?term=blah&term2=cool

The GET method is independent of PHP, and is part of the HTTP specification.

PHP handles GET requests easily by automatically creating the superglobal variable $_GET[], where each array index is a GET variable name and the value of the array index is the value of the variable.

Here is some demo code to show how this works:

<?php
    //check if the get variable exists
    if (isset($_GET['search']))
    {
        search($_GET['search']);
    }

    function Search($res)
    {
        //real search code goes here
        echo $res;
    }


?>

<a href="?search=15">Search</a>

which will print out 15 because it is the value of search and my search dummy function just prints out any result it gets
