Question

I have a PHP array that looks like that:

$array = Array
(
    [teamA] => Array
    (
        [188555] => 1
    )
    [teamB] => Array
    (
        [188560] => 0
    )
    [status] => Array
    (
        [0] => on
    )
)

In the above example I can use the following code:

echo $array[teamA][188555];

to get the value 1.

The question now, is there a way to get the 188555 in similar way;

The keys teamA, teamB and status are always the same in the array. Alse both teamA and teamB arrays hold always only one record.

So is there a way to get only the key of the first element of the array teamA and teamB?

Answer 1

echo array_keys($array['teamA'])[0];
