Hello Readers,
If we want to remove the duplicate values present in an array then their is a function named array_unique() that we can use .
If two or more array values are the same, the first appearance value will be kept and the other will be removed.
Example :
<?php
$a=array("a"=>"red","b"=>"green","c"=>"red");
print_r(array_unique($a));
?>
Output:
Array ( [a] => red [b] => green )
