Introduction

PHP is a server scripting language, and It is a powerful tool for making interactive and dynamic Web-pages. I have used WampServer 2.2 for following excercise..

<?php
function remove_duplicates_list($list1) {
  $nums_unique = array_values(array_unique($list1));
  return $nums_unique ;
}
$nums = array(2,3,4,5,1,2,3,4);
print_r(remove_duplicates_list($nums));
?>

Result
