使用键过滤多维数组

Question

I need help from the PHP experts there. I want to do some filters in this result. I want to filter it using the key custom_search_emp_id_11 . hope there's a shorter/one liner code/function to do filters? thank you in advance for the answers!

Array
(
    [0] => stdClass Object
        (
            [custom_search_emp_id_11] => flag_emp_id_11
            [custom_search] => flag_emp_id_11
            [eti_id] => 1
            [time] => 1:00
            [emp_id] => 11
        )
    [1] => stdClass Object
        (
            [custom_search_emp_id_22] => flag_emp_id_22
            [custom_search] => flag_emp_id_22
            [eti_id] => 4
            [time] => 1:00
            [emp_id] => 22
        )
    [2] => stdClass Object
        (
            [custom_search_emp_id_33] => flag_emp_id_33
            [custom_search] => flag_emp_id_33
            [eti_id] => 5
            [time] => 1:00
            [emp_id] => 33
        )
    [3] => stdClass Object
        (
            [custom_search_emp_id_11] => flag_emp_id_11
            [custom_search] => flag_emp_id_11
            [eti_id] => 1
            [time] => 1:00
            [emp_id] => 11
        )
)

and the output will be :

Array
(
    [0] => stdClass Object
        (
            [custom_search_emp_id_11] => flag_emp_id_11
            [custom_search] => flag_emp_id_11
            [eti_id] => 1
            [time] => 1:00
            [emp_id] => 11
        )

    [3] => stdClass Object
        (
            [custom_search_emp_id_11] => flag_emp_id_11
            [custom_search] => flag_emp_id_11
            [eti_id] => 2
            [time] => 1:00
            [emp_id] => 11
        )
)

You can use array_filter with a function that checks for the existence of the custom_search_emp_id_11 key in the objects:

$filtered_array = array_filter($array, function ($v) { return isset($v->custom_search_emp_id_11); });
