Removing pages can be done with removePage() or
removePages(). The first method accepts a an instance
of a page, or an integer. The integer corresponds to the
order a page has. The latter method will remove all
pages in the container.
Example 618. Removing pages from a container
<?php
$container = new Zend_Navigation(array(
array(
'label' => 'Page 1',
'action' => 'page1'
),
array(
'label' => 'Page 2',
'action' => 'page2',
'order' => 200
),
array(
'label' => 'Page 3',
'action' => 'page3'
)
));
// remove page by implicit page order
$container->removePage(0); // removes Page 1
// remove page by instance
$page3 = $container->findOneByAction('Page 3');
$container->removePage($page3); // removes Page 3
// remove page by explicit page order
$container->removePage(200); // removes Page 2
// remove all pages
$container->removePages(); // removes all pages
