cleaning same values in array

I want to clear same values in array. For example so be my array:

array(0=>"1",1=>"1",2=>"3",3=>"1",4=>"6");

I wan开发者_开发技巧t ot get as:

array(0=>"1",1=>"3",2=>"6");

How?

---

<?php
$input = array(0=>"1",1=>"1",2=>"3",3=>"1",4=>"6");
$result = array_values(array_unique($input));
print_r($result);
?>

array_unique

Array
(
    [0] => 1
    [2] => 3
    [4] => 6
)

array_values with array_unique

Array
(
    [0] => 1
    [1] => 3
    [2] => 6
)

With a combination of array_unique ^[docs] and array_values ^[docs]:

$array = array_values(array_unique($array));

I believe you want the array_unique() function ( http://php.net/manual/en/function.array-unique.php ):

$arr = array_unique(array(0 => '1', 1 => '1', 2 => '2'));

will return:

array(0=> '1', 2 => '2')

I believe you can use array_slice for this purpose. Then edit the keys' values manually

Edit: To remove a key/value pair, call the unset() function on it. from here under Creating/modifying with square bracket syntax section.
