How to format the result of var dump (array)-CodePudding

I have this code, which gets an array from a API URL.

                 <?php
                 $url = 'https://api.example.com/v1/w';
                 $data = file_get_contents($url);
                 $data = json_decode($data);
                 echo '<pre>' , var_dump($data->rule->deny_countries) , '</pre>';
                 ?>

It displays this:

       array(3) {
       [0]=>
       string(2) "US"
       [1]=>
       string(2) "ES"
       [2]=>
       string(2) "MX"
      }

How can I only print the values of the strings? ( US, ES, and MX ) that are country codes, and i want to convert them to the full country name, example: United States, Spain, Mexico.

You can print country code with this code:

$country_code = $data->rule->deny_countries;
echo $country_code[0]; // print US
echo $country_code[1]; // print ES
// ecc.

You can create an array to convert country code to country name like this:

$country_name = array("US"=>"United States", "ES"=>"Spain", "MX"=>"Mexico");

And then you can print country name with this code

echo $country_name[$country_code[0]]; // print United States
echo $country_name[$country_code[1]]; // print Spain
// ecc.

Thank you to @Stefino76, this is working code:

    <?php

     $url = 'https://api.example.com/v1/9d';
     $data = file_get_contents($url);
     $data = json_decode($data);
     
     $country_code = $data->rule->deny_countries;

     $country_name = array("US"=>"United States", "ES"=>"Spain", "MX"=>"Mexico");
     $img_file = array("AX"=>"united-states.png", "AD"=>"sp.png", "AS"=>"mx.png");
     echo '<div><img src="'.$img_file[$country_code[0]].'">'.$country_name[$country_code[0]].'</div>'; 
     echo '<div><img src="'.$img_file[$country_code[1]].'">'.$country_name[$country_code[1]].'</div>'; 
     echo '<div><img src="'.$img_file[$country_code[2]].'">'.$country_name[$country_code[2]].'</div>';
