loop through array of objects

Question

I Have an array called $pages content is as follows:

Array
(
[01-about-us] => Page Object
    (
        [_uri] => about-us
        [_menuItem] => 01
        [_visable] => 1
    )

[02-contact] => Page Object
    (
        [_uri] => contact
        [_menuItem] => 02
        [_visable] => 1
    )

[_sitemap] => Page Object
    (
        [_uri] => sitemap
        [_menuItem] => 
        [_visable] => 
    )

[home] => Page Object
    (
        [_uri] => home
        [_menuItem] => 
        [_visable] => 1
    )
)

is there an easy way to loop through and get page objects by there properties ie:

<?php foreach($pages->_visible() AS $p): ?>
  <li> page </li>
<?php endforeach ?>

Answer 1

No. You will have to use an if:

foreach ($pages as $page) {
    if ($page->_visible == 1) {
        echo "<li>page</li>";
    }
}

(Note also you misspelt visible in the array, perhaps a typo?)

Answer 2

Or you can utilize PHP's array_filter function:

$pagesVisible = array_filter($pages, function($page) {
    return (bool) $page->_visible;
});

foreach ($pagesVisible as $key => $page) {
    print '<li>' . $key . '</li>';
}

Or shorthand it to:

$filter = function($page) {
    return (bool) $page->_visible;
};
foreach (array_filter($pages, $filter) as $key => $page) {
    print '<li>' . $key . '</li>';
}
