You can use the array_unique function to remove duplicate values from an array. This function will return a new array that only contains unique values from the original array.

Example usage:

<?php
$array = array(1, 2, 3, 2, 4, 3);
$array = array_unique($array);

print_r($array);
?>

Output result:

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

In the example above, the duplicate values 2 and 3 in the original array were removed, and a new array was returned.
