        unset($arr[$current]);
        foreach ($arr As $user => $friends) {
            $common = array();
            $total = array();
            foreach ($friends As $friend) {
                if (in_array($friend, $cUser)) {
                    $common[] = $friend;
                }
            }
            $total = count($common);
            $add = ($total != 1) ? 's' : '';
            $final[] = "<i>{$current} has {$total} friend{$add} in common with {$user}.</i>";
        }
        return implode('<br />', $final);
    }

# Array of users and friends
    $Friends = array(
        "Rana" => array("Pothik", "Zaman", "Tanmoy", "I****a"),
        "Nandini" => array("Bonna", "Shakib", "Kamal", "Minhaj", "I****a"),
        "Roni" => array("Akbar", "Anwar", "Khakan", "Pavel"),
        "Liton" => array("Mahadi", "Pavel"),
        "Mamun" => array("Meheli", "Tarek", "Zaman")
    );

# Creating the output value
    $output = "<ul>";
    foreach ($Friends As $user => $friends) {
        $total = count($friends);
        $common = findCommon($user, $Friends);
         $output .= "<li><u>{$user} has {$total}  friends.</u><br /><strong>Friends:</strong>";
        if (is_array($friends) && !empty($friends[0])) {

        $output .= "{$common}<br /><br /></li>";
    }
    $output .= "</ul>";

# Printing the output value
    print $output;
        ?>

This is an exercise in use of functions and arrays. You're on the right lines with the function to produce an array of friends for a given name but you're trying to do too much in the function -- just return the array (no html, no added strings) and let the calling code decide what to do next. Take the problems one by one. Do the function and test it for the first requirement. Then expand the calling code to do the second requirement. Finally, create the form and add it to the code you've written. POST and GET aren't functions by the way, they're the method you put on the form.
