Question

I have this:

Array
(
    [carx] => Array
        (
            [no] => 63

        )

    [cary] => Array
           (
           [no] => 64

           )
)

How can I find the key carx when i have the no=63 ? i know how to use array_search() but this one is a bit tricky. Like i can find key name id while I have 63 But this one is a bit tricky.

can someone help me ?

Answer 1

foreach ($array as $i => $v) $array[$i] = $v['no'];
$key = array_search(63, $array);
