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

In PHP, you can deduplicate arrays using the built-in function array_unique(). This function takes an array as input and returns a new array with duplicates removed.

Here's an example of how to use array_unique() to deduplicate an array:

<?php $array = [1, 2, 2, 3, 4, 4, 5]; $unique_array = array_unique($array); print_r($unique_array); ?>

The result of the above code will be:

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