Merging two variables? (?)

[omgwtf]

Ok, this is a little complicated. Well, atleast to me it is.

I'm trying to make a user-defined menu. Where a registered user can choose what the menu should look like. As in, which components go where.

First, I defined the single menu elements. Such as,

function user_menu_1()
{
  echo "bla";
}

function user_menu_2()
{
 echo "sdfmsdaf";
}

function user_menu_3()
{
 echo "this is module/component 3";
}

Now, what the selected are stored in a mysql database. Just the number of the menu.

Heres what the query looks like, basicly:

			$user_menu_query = "SELECT user_menu1, user_menu2, user_menu3, user_menu4, user_menu5, user_menu6, user_menu7, user_menu8, user_menu9, user_menu10, user_menu11, user_menu12, user_menu13, user_menu14 FROM ".$user_menu_table." WHERE user_ID = '$user_ID' ";
			$user_menu_result = mysql_query ($user_menu_query);
			while ($menu_row = mysql_fetch_assoc ($user_menu_result)) {

user_menu1 would be the first menu to show. So, if user_menu1 would = 3. It should show user_menu_3();

How do I code this?

Is there an easier way than doing

				if ($menu_row_1 = "1") {
					echo user_menu_1();
				}
				if ($menu_row_1 = "2") {
					echo user_menu_2();
				}

?

Like this:

function user_menu_2()
{
    return 'Hello';
}

$menu_row_1 = '2';
$var_func = 'user_menu_' . $menu_row_1;
echo $var_func();

// echos "Hello"
