unset the array

Question

I have two arrays. I'd like to merge them into one, but remove the redundant values. How can I do this?

Answer 1

Use array_unique function .

Example

<?php
$input = array("a" => "green", "red", "b" => "green", "blue", "red");
$result = array_unique($input);
print_r($result);
?>

Output:

Array
(
    [a] => green
    [0] => red
    [1] => blue
)
