Question

Suppose I have a link and a function as below, how can I map this link with the function?

As a result, user click on the link “remove user” will execute the function “remove_user

<a href="xxx">remove all compare items</a>

functio remove_user() {
return mysql_query("DELETE * FROM compre_items");
}

Answer 1

You will have to do something like this:

<a href="?action=delete">remove user</a>
<?php
    if ($_GET['action'] == 'delete') {
        mysql_query("DELETE FROM user WHERE id = 0");
    }
?>

But this is not good pattern/style to develop web applications.

Check out MVC pattern to separate business and presentation logic. Than MVC frameworks like Zend Framework, Cake PHP or others.
