$json = '{
    "currency": {
        "19:15": {
            "1": "1.20585"
        },
        "19:14": {
            "1": "1.22585"
        }
    }
}';

I want to retrieve value "1.20585" out of this array in PHP.

The time "19:15" changes every minute, but I want always the upper first one (most recent).

$array["currency"][0]["1"] didn't solve it for me. Does someone know one-line solution that will retrieve the value?

So for you `$first = reset($array["currency"]);` then `echo $first[1];` – AbraCadaver May 03 '21 at 17:29
You can use `reset` as @AbraCadaver said, but you first have to use `json_decode` to get the associative array. Demo: https://3v4l.org/K8YgV – Kim Hallberg May 03 '21 at 18:08
What everyone is saying, plus the marked duplicate, plus recursion. – Sammitch May 03 '21 at 18:55
