In PHP, how do I deduplicate arrays with examples?

In PHP, you can deduplicate arrays using different methods. Below are some examples demonstrating how to achieve this:


        // Example 1: Using array_unique()
        $array = array(1, 2, 2, 3, 4, 4, 5);
        $deduplicatedArray = array_unique($array);
        print_r($deduplicatedArray);
        
        // Example 2: Using array_flip()
        $array = array("apple", "orange", "banana", "apple");
        $deduplicatedArray = array_keys(array_flip($array));
        print_r($deduplicatedArray);
