In PHP 8.4 & PHP 8.3, you can remove duplicate elements from an array using the `array_unique()` function. This function takes an array as input and returns a new array with duplicate values removed.Heres how you can do it in PHP 8.4 & PHP 8.3:

<?php// Sample array with duplicate elements$array = [1, 2, 2, 3, 4, 4, 5];// Remove duplicate elements$uniqueArray = array_unique($array);// Print the resulting arrayprint_r($uniqueArray);?>

Output:

Array([0] => 1[1] => 2[3] => 3[4] => 4[6] => 5)

Explanation:* `array_unique()` removes duplicate values from the array.* The keys of the original array are preserved. If you want to reindex the array, you can use `array_values()`:

<?php// Reindex the array$reindexedArray = array_values($uniqueArray);// Print the reindexed arrayprint_r($reindexedArray);?>

Output:

Array([0] => 1[1] => 2[2] => 3[3] => 4[4] => 5)

This will give you an array with unique elements and reindexed keys.
