In PHP, how do I deduplicate arrays in Symfony?

In Symfony, you can deduplicate arrays using functions like array_unique. This is a common requirement when dealing with collections of data where you want to ensure each item is represented only once. Here's how to do it:


        $array = ['apple', 'banana', 'apple', 'orange', 'banana'];
        $deduplicatedArray = array_unique($array);
        print_r($deduplicatedArray);
        // Output: Array ( [0] => apple [1] => banana [3] => orange )
