Re: [PHP] Re: How do I remove an array element from within a recursive function? [solved]

[Daevid Vincent]

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
)
