Get a Random Number out of an Array?

Hi, I basically want to get a random number, but I want this number to be in an array.

Basically...

PHP:

$ids = [3,5,27,53,87]



Then, I need to get a random number that is one of the ints in that array..

Also, if you can tell me, how can I make an inventory array with lots of random numbers to put in a chest?

So I have an array with the ids and data... I need help putting that in a big array.. (Separate for ids and data), then convert those 2 arrays in a inventory format so I can use setInventory() with that!

Thanks in advance!!

OK ty!

OK ty! I'm not sure how to convert to inventory format though!

What is inventory format?

Btw...

Personally I like this more because it is faster.

PHP:

function random_array_value(array $array){
    return $array[array_keys($array)[mt_rand(0, count($array))]];
}

Basically, you know when you do

PHP:

$player->getInventory()->getContents(); 

That returns an array, that is in a format that allows to to do

PHP:

$player>getInventory()->setContents();

It's not called "format". It is called data type

Use this:

PHP:

$id = $ids[mt_rand(0, count($ids)];
$inventory->addItem(Item::get($id));

OK, but is there a way to do it like that? I want the items to be in random slots

PHP:

$inventory->setItem(mt_rand(0, $inventory->getSize() - 1), $item);

OK thanks.
