在不使用foreach循环的情况下访问3d数组

Question

Let's say I have a 3D array and I don't want to access it through the key names.

Is there a way to access to the value (2) without having to use a foreach loop?

array (size=1)
'type' => 
 array (size=1)
  'registered' => string '2' (length=1)

Answer 1

It is not possible without a loop.

1. If you don't want to use keys and all that matters is the position within the array then use a numerical array.
2. If you really want to use an associative array and you need to find the key at a specified index, then at some point you will need to loop through your array.

Answer 2

You could try serializing your array and working with the serialized structure. Not saying this is good or even viable, but it might do what you want.
