In PHP, how do I deduplicate strings in vanilla PHP?

Deduplicating strings in PHP can be achieved using various methods. One common way is to use the `array_unique()` function, which returns an array with duplicate values removed. Here's an example:


        <?php
        function deduplicateStrings($array) {
            return array_unique($array);
        }

        $strings = ["apple", "banana", "apple", "orange", "banana", "grape"];
        $uniqueStrings = deduplicateStrings($strings);

        print_r($uniqueStrings); // Output: Array ( [0] => apple [1] => banana [3] => orange [5] => grape )
        ?>
