Remove duplicate values from a multidimensional array in PHP

Question

How can I remove duplicate values from a multidimensional array in PHP like below.

I tried Remove duplicate value in multidimensional array. But did not solve my problem.

Array(
    [0] => outdoor
    [1] => indoor
)

Array(
    [0] => indoor
)

Result should be a single array like below :

 array(outdoor,indoor);

Show the original array exactly, or the answer in the post mentioned should work. — xdazz, Mar 20 '14 at 05:35
@xdazz please refer top array set. this is what i get as a result array. — Mahesh, Mar 20 '14 at 05:37
@xdazz yes. i'm using Advanced custom field repeater. and it gives an array like this. — Mahesh, Mar 20 '14 at 05:39

Use array_unique to remove duplicates from a single array.

Use array_merge to combine arrays.

Try:

array_unique(array_merge($array1,$array2), SORT_REGULAR);

`$array1 = array( 0 => 'outdoor', 1 => 'indoor' );` `$array2 = array( 0 => 'indoor' );` – tchow002 Mar 20 '14 at 05:44

$array = array(array("outdoor","indoor"),array("indoor"));

$result = array_unique($array);

print_r($result[0]);

Try this:

<?php
$Arr = array(array('outdoor','indoor'),array('indoor'));
$result = array_unique($Arr);

$newArr = $result[0];

echo '<pre>';
print_r($newArr);
?>

The result will be

Array
(
    [0] => outdoor
    [1] => indoor
)

Thanks
