Search array of dates does not return result

Question

Hello I am trying to search for an hour based on the current date with the following function:

$key = array_search($todayday, array_column($days, 'date', 'hours'));

Where $todayday is equal to today day which comes from the sever day date.

the Array $days is:

                 Array
(
    [0] => Array
        (
            [date] => 01
            [hours] => 0
        )

    [1] => Array
        (
            [date] => 02
            [hours] => 8
        )

    [2] => Array
        (
            [date] => 03
            [hours] => 16
        )

    [3] => Array
        (
            [date] => 04
            [hours] => 24
        )

    [4] => Array
        (
            [date] => 05
            [hours] => 32
        )

    [5] => Array
        (
            [date] => 06
            [hours] => 40
        )

    [6] => Array
        (
            [date] => 07
            [hours] => 40
        )
... etc....

while $todaydate is equal to 1,2,3,4,5 it works. but for 6 and 7 does not return anything. Any help is welcome to resolve this issue. Thanks

I suspect that since date = 6 and 7 have the same value of hours this is why it does not return anything but the question is how to return it actually.

Your supposition is correct, you can not have duplicate keys. Use the key from the search and then access hours:

$key   = array_search($todayday, array_column($days, 'date'));
$hours = $days[$key]['hours'];

Or shorter:

$hours = $days[array_search($todayday, array_column($days, 'date'))]['hours'];

In the case where the indexes are not 0 based and sequential, use array_values() to re-index:

$days  = array_values($days);
$key   = array_search($todayday, array_column($days, 'date'));
$hours = $days[$key]['hours'];
