Many times we need to array has duplicate values or not. Using php language this is very easy.

For checking the duplicate array value array_unique function is very useful.

Here I am giving you very simple php example:

<?php
 $array1 = array("banana","apple","pear","banana");

 if (count(array_unique($array1)) < count($array1))
 echo 'Duplicate entry found in array';
 else
 echo 'No Duplicate values found in array';
 ?>

Output:  Duplicate entry found in array
