I want to remove elements from array dates which are not present in finald array. I am using the following code :

$tags = array_diff($dates, $finald);

I am getting the following array

Array
(
    [0] => 2015-07-02
    [1] => 2015-07-03
    [2] => 2015-07-04
    [3] => 2015-07-05
    [4] => 2015-07-06
    [6] => 2015-07-08
    [7] => 2015-07-09
    [8] => 2015-07-10
    [9] => 2015-07-11
    [10] => 2015-07-12
    [11] => 2015-07-13
    [13] => 2015-07-15
    [15] => 2015-07-17
    [16] => 2015-07-18
    [17] => 2015-07-19
    [18] => 2015-07-20
    [20] => 2015-07-22
    [22] => 2015-07-24
    [23] => 2015-07-25
    [24] => 2015-07-26
    [25] => 2015-07-27
    [27] => 2015-07-29
    [29] => 2015-07-31
    [30] => 2015-08-01
    [5] => 2015-07-06
    [12] => 2015-07-13
    [14] => 2015-07-15
    [19] => 2015-07-20
    [21] => 2015-07-22
)

I am not getting Why 16-07-2015 and 23-07-2015 is removed from the final tags array

remove elements from array dates which are not present in finald

So, save that are in both arrays?

$dates = Array
    (
        '2015-07-02',        
        '2015-07-03');
$finald =  array(
        '2015-07-02',        
        '2015-07-07');
print_r(array_intersect($dates, $finald));

result

Array ( [0] => 2015-07-02 )
