I need to remove array item with given value:
if (in_array($id, $items)) {
$items = array_flip($items);
unset($items[ $id ]);
$items = array_flip($items);
}
Could it be done in shorter (more efficient) way?

It can be accomplished with a simple one-liner.
Having this array:
$arr = array('nice_item', 'remove_me', 'another_liked_item', 'remove_me_also');
You can do:
$arr = array_diff($arr, array('remove_me', 'remove_me_also'));
And the value of $arr
will be:
array('nice_item', 'another_liked_item')
