How to get key value in Redis?

Question

PHP

Hello!
There is an array:

$array = [
    "key1" => ["value1"=>1, "value2"=>2, "value3"=>3, "value4"=>4],
    "key2" => ["value6"=>6, "value7"=>7, "value8"=>8, "value9"=>9],
];

Writing in redis:
$redis->set('keys',$array);
So how can you get, find the desired value, for example - value1?
