This guide demonstrates how to filter traits in a memory-efficient way using PHP.


        <?php
        trait FilterTrait {
            public function filter(array $items, callable $callback) {
                return array_filter($items, $callback);
            }
        }

        class ItemProcessor {
            use FilterTrait;

            public function processItems(array $items) {
                return $this->filter($items, function($item) {
                    return $item > 10; // Example condition
                });
            }
        }

        $processor = new ItemProcessor();
        $filteredItems = $processor->processItems([5, 10, 15, 20]);
        print_r($filteredItems);
        ?>
