This is how you use the class:

# Include the class file
include("menu.php");
# define your menu as array
$myMenu=array("one"=>"one.html","two"=>"two.html","three.html");
$label="Hello World!";
# this creates a left aligned menu
$a=new tabMenu($myMenu,$label,0,"left");
# this creates a right aligned menu
$b=new tabMenu($myMenu,$label,0,"right");
# this creates a centered menu
$c=new tabMenu($myMenu,$label,0);
