Tips for styling the output of var_dump with an array

I currently have a script that retrieves an array from an 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>';
                 ?>

The output looks like this:

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

How can I extract only the country code values (US, ES, and MX), convert them into the full country names (United States, Spain, Mexico), and display them?

Answer №1

To retrieve the country code, you can use the following code snippet:

$country_code = $data->rule->deny_countries;
echo $country_code[0]; // displays US
echo $country_code[1]; // displays ES
// and so on.

If you want to convert the country code into the country name, you can create an array like this:

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

You can then print the country names using the following code:

echo $country_name[$country_code[0]]; // displays United States
echo $country_name[$country_code[1]]; // displays Spain
// and so on.
