In PHP, how do I deduplicate strings for production systems?

In production systems, it's essential to remove duplicate strings to maintain data integrity and optimize performance. Below is an example of how to deduplicate strings in PHP using built-in functions.


        <?php
        // Sample array of strings
        $strings = ["apple", "banana", "apple", "orange", "banana", "grape"];
        
        // Use array_unique to deduplicate strings
        $uniqueStrings = array_unique($strings);
        
        // Display unique strings
        print_r($uniqueStrings);
        ?>
