Zend_Navigation_Container implements
RecursiveIteratorIterator, and can be
iterated using any Iterator class. To iterate
a container recursively, use the
RecursiveIteratorIterator class.
Example 620. Iterating a container
<?php
/*
* Create a container from an array
*/
$container = new Zend_Navigation(array(
array(
'label' => 'Page 1',
'uri' => '#'
),
array(
'label' => 'Page 2',
'uri' => '#',
'pages' => array(
array(
'label' => 'Page 2.1',
'uri' => '#'
),
array(
'label' => 'Page 2.2',
'uri' => '#'
)
)
),
array(
'label' => 'Page 3',
'uri' => '#'
)
));
// Iterate flat using regular foreach:
// Output: Page 1, Page 2, Page 3
foreach ($container as $page) {
echo $page->label;
}
// Iterate recursively using RecursiveIteratorIterator
$it = new RecursiveIteratorIterator(
$container, RecursiveIteratorIterator::SELF_FIRST);
// Output: Page 1, Page 2, Page 2.1, Page 2.2, Page 3
foreach ($it as $page) {
echo $page->label;
}
