Use the PHP array_unique() function

You can use the PHP array_unique() function to remove the duplicate elements or values form an array. If the array contains the string keys, then this function will keep the first key encountered for every value, and ignore all the subsequent keys. Here's an example:

<?php
$array = array("a" => "moon", "star", "b" => "moon", "star", "sky");
 
// Deleting the duplicate items
$result = array_unique($array);
print_r($result);
?>
