How to properly format a JSON array | PHP

Essentially I have the following array with various values that are being passed through a function. The output of each needs to then be assembled into a JSON Array that looks like the following:

  "response": {
    "firstvalue": 4,
    "secondvalue": 1,
    "thirdvalue": "String Response 1",
    "fourthvalue": "String Response 2"
  }

Code So Far:

   <?php
    header('Content-Type: application/json');
    
    $arrayvalues = 
    ["34jkw9k2k9w", 
    "k4otk320el01oeoo20", 
    "30f0w2l020wk3pld==", 
    "3c2x3123m4k43=="];
    
    foreach($arrayvalues as $item) {
        $decrypted = myFunction($item, $action = 'decrypt');
        $response["firstvalue"] = $decrypted;
        $response["secondvalue"] = $decrypted;
        $response["thirdvalue"] = $decrypted;
        echo json_encode($response);
    }
    
    ?>

How can this be done?

Confusion between commands.Bot and discord.Client | Which one should I use?

Whenever you look at YouTube tutorials or code from this website there is a real variation. Some developers use client = discord.Client(intents=intents) while the others use bot = commands.Bot(command_prefix="something", intents=intents) . Now I know slightly about the difference but I get errors from different places from my code when I use either of them and its confusing. Especially since there has a few changes over the years in discord.py it is hard to find the real difference. I tried sticking to discord.Client then I found that there are more features in commands.Bot . Then I found errors when using commands.Bot . An example of this is: When I try to use commands.Bot client = commands.Bot(command_prefix=">",intents=intents) async def load(): for filename in os.listdir("./Cogs"): if filename.endswith(".py"): client.load_extension(f"Cogs.{filename[:-3]}") The above doesnt giveany response from my Cogs ...
