Question

I am exercising some PHP OOP and therefore I am creating a class to create a simple navigation menu ( with extensions in the future ) now I have build this class that works kinda.. with 1 menu item tough.. I don;t know how to use arrays in my class to use the class like

<?php
$menu = new Navigation("Test", "mainmenu");

$menu->setMenuItem("home", "test");
echo $menu->display();

?>

as you see I should be able to give each menu item with the setMenuItem(); method.
but since it does not use Arrays at the moment I only get the first value

The class itself is as follows:

<?php
class Navigation implements navigationInterface {

    public $menu = null;
    public $name = null;
    public $klasse = null;

    public function __construct($name, $klasse) {

        $this->name = $name;
        $this->klasse = $klasse;

    }

    public function getName() {
        return $this->name;
    }

    public function getClass() {
        return $this->klasse;
    }

    public function setMenuItem($items) {
        $this->menuItem = $items;
    }

    public function getMenuItem() {
        return $this->menuItem;
    }

    public function display() {

        $menu = '<nav class="' . $this->getName() . '">';
        $menu .= '<li><a class="' . $this->getClass() . '" href="index.php?page=' . $this->getMenuItem() . '.php">' . $this->getMenuItem() . '</a></li>';
        $menu .= '</nav>';

        return $menu;

    }
}
?>

who can show me how to use arrays within the class in combination with a loop to create a menu with all given values?

Thanks in advance.

<?php
class Navigation{

    public $menu = null;
    public $name = null;
    public $klasse = null;

    public function __construct($name, $klasse) {

        $this->name = $name;
        $this->klasse = $klasse;

    }

    public function getName() {
        return $this->name;
    }

    public function getClass() {
        return $this->klasse;
    }

    public function setMenuItem($items) {

        $this->menuItem = $items;
    }

    public function getMenuItem($menu) {
        return $menu;
    }

    public function display() {

        $menu = '<nav class="' . $this->getName() . '">';
        if(is_array($this->menuItem))
        {
        foreach($this->menuItem as $val)
        {
        $menu .= '<li><a class="' . $this->getClass() . '" href="index.php?page=' . $this->getMenuItem($val) . '.php">' . $this->getMenuItem($val) . '</a></li>';
        }
        }
        else{
            $menu .= '<li><a class="' . $this->getClass() . '" href="index.php?page=' . $this->getMenuItem($this->menuItem) . '.php">' . $this->getMenuItem($this->menuItem) . '</a></li>';

        }


        $menu .= '</nav>';

        return $menu;

    }
}
?>

<?php
$menu = new Navigation("Test", "mainmenu");

$menu_items=array("home","test");
$menu->setMenuItem($menu_items);

echo $menu->display();

?>
