OMG! How retarded am I. Duh. of course... For some reason I thought you
could use the & reference because it was a "pointer" to the actual
object
menuItem::removeMenuItems($navArray['dart'], array('Login',
'Lost Password'));
public static final function removeMenuItems(&$menuItems, $removeArray)
{
foreach($menuItems as $key => $value)
if (is_array($value->children))
menuItem::removeMenuItems($value->children,
$removeArray);
elseif (in_array($value->menu, $removeArray))
unset($menuItems[$key]);
}

You don't unset the value, you unset the key.
<?php
$items = array('menu1', 'menu2', 'menu3');
echo "Before:\n";
print_r($items);
foreach ($items as $_menuKey => $value) {
if ($value == 'menu2') {
unset($items[$_menuKey]);
}
}
echo "After:\n";
print_r($items);
$ php test.php
Before:
Array
(
[0] => menu1
[1] => menu2
[2] => menu3
)
After:
Array
(
[0] => menu1
[2] => menu3
)
