Solved Two Arrays inside an Array

okay so I know it looks dumb, but basically.. how would I make this(its an example without code on php.net)

Code:

Ban:
- Reason: BL394D
- Reason: BL4438H

In my YAML

PHP:

  ["Ban"]=>
  array() {
    [0]=>
    array(4) {
      ["Reason"]=>
      string(6) "BL394D"
    }
    [1]=>
    array() {
      ["Reason"]=>
      string(7) "BL4438H"
    }
  }

So once some gets banned , I get the reason and I throw it into his Ban array. I know how to do that. Though I don't know how to set the second one without overwriting

 

you can append values to the array

PHP:

/** @var array $ban_array */
$ban_array[]["Reason"] = "Hello";


 

It still overrides the first one

 

I just used an ENUM config for every player, it is easier that way.
