Error when trying to echo values from a data

Question

I'm getting an error when trying to call for data using echo.

{
  "prefix": "_country-",
  "countries": [
    {
      "code": "al",
      "name": "Albania",
      "cities": {
        "prefix": "_city-",
        "options": [
          {
            "code": "durres"
          },
          {
            "code": "tirana"
          }
        ]
      }
    },
    {
      "code": "dz",
      "name": "Algeria",
      "cities": {
        "prefix": "_city-",
        "options": [
          {
            "code": "algiers"
          },
          {
            "code": "oran"
          }
        ]
      }
    }
  ]
}

My goal is to get those data above and expect it to loop until its last data using this code:

`foreach($countryarr1['countries'] as $countkey1 => $countname1){ ?> <br><br> <?php 
  foreach($countname1['cities'] as $cntrykey2 => $cntrys){
    foreach($cntrys['options'] as $optionskey1 => $optionsarr1){
      var_dump($optionsarr1);
    }
  }
}`

It returns this error

'Fatal error: Uncaught TypeError: Cannot access offset of type string on string in 
C:\xampp\htdocs\homepage\countries.php:25 Stack trace: #0 {main} thrown in 
C:\xampp\htdocs\homepage\countries.php on line 25'

Here is the line 25

Error on line 25

Am I missing something? By the way I'm working on a proxy dashboard for a website.

Here's proof that when I only had 2 arrays it had no problems:

foreach for 2 arrays

output with no errors

Now when I add another foreach on the 3rd array and so forth, there's the error. Here it is.

foreach for 3rd array

And the error error

I had no problems when doing this on 2 arrays, now I'm at 4 arrays I really don't know what am I missing out. Would really appreciate your help! — Heinrich Picar, Dec 05 '21 at 12:59
What have you tried to resolve the problem? The given code does not contain a line 25, so it's pretty hard to see why it fails — Nico Haase, Dec 05 '21 at 13:03
My bad, here is the line 25 https://i.stack.imgur.com/8c4r9.png — Heinrich Picar, Dec 05 '21 at 13:33

Your are using foreach on object cities. Either make cities array or access cities directly.

$countname1['cities'] OR $countname1.cities
