array_push和> =不工作

Heyo! I've never knew this actually but the following method doesn't seem to work properly.

array_push($items[$key], 'price' => 100);

How can I push it in an array so it displays, {'price':100, 'moredata':1231}

What am I missing?

You can't specify a key with array_push.

Fortunately, most of the time* when people use array_push it isn't actually necessary.

$items[$key]['price'] = 100
