removing duplicates from an array in php

I want to remove duplicate elements from an array in php. Following is the structure of the array

Array
(
    [0] => Array
        (
            [0] => [email protected]
            [1] => [email protected]
            [2] => [email protected]
            [3] => [email protected]
            [4] => [email protected]
            [5] => [email protected]
            [6] => [email protected]
            [7] => [email protected]
        )

)

How to go about it ?

No array_unique() solution. not so smart:)

array_keys(array_flip($array));

If use your array, $array = $yourArray[0];

Try array_unique.

Code :

<?php

$arr = array_unique($arr);

?>

array array_unique ( array $array [, int $sort_flags = SORT_STRING ] )

Takes an input array and returns a new array without duplicate values.

$new_unique_array = array_unique($your_array[0]);

Hope that helps, Stefan

Try array_unique():

$newArray = array_unique($oldArray);

From the docs:

[array_unique()] Takes an input array and returns a new array without duplicate values.
