$_callback
$_callback : callable
The callback used to filter the elements in this collection
Creates a filtered iterator from another iterator. The filtering is done by passing a callback function to each of the elements and taking them out if it does not return true.
__construct(\Traversable|array $items, callable $callback)
Creates a filtered iterator using the callback to determine which items are accepted or rejected.
Each time the callback is executed it will receive the value of the element in the current iteration, the key of the element and the passed $items iterator as arguments, in that order.
