How do I remove duplicates from an array in PHP?

Removing duplicates from an array in PHP can be easily achieved using the built-in array_unique function. This function takes an array as input and returns a new array with duplicate values removed. Below is an example demonstrating how to use this function.


        <?php
        // Sample array with duplicates
        $array = array(1, 2, 2, 3, 4, 4, 5);
        
        // Removing duplicates
        $uniqueArray = array_unique($array);
        
        // Displaying the result
        print_r($uniqueArray);
        ?>
