Unable to Access API Key with PHP…any idea what's up?

Question

I am a junior programmer. Recently I've been trying to develop in PHP. I am trying to create a basic page about countries. For some reason I cannot grab the information from this API page. Can anyone give me some tips?

Here is what a sample country array looks like. Ideally I would like to try to grab the "name" attribute.

Here is my HTML and PHP:

<?php

if(!empty($_GET['country'])) {
$country_url = 'https://restcountries.eu/rest/v1/name/' . urlencode($_GET['country']) . '?fullText=true';
$country_json = file_get_contents($country_url);
$country_array = json_decode($country_url, true);
           }

?>

 <!DOCTYPE html>
     <html lang="en">
        <head>
            <meta charset = "utf-8" />
            <title> PHP Country Practice </title>
        </head>
     <body>
        <form action="">
            <input type = "text" name = "country" />
            <button type="submit">submit </button>
        </form>

<?php

if(!empty($country_array)) {
    echo '<p> $country_array['name'] </p>';
    }
    ?>
</body>
</html>

Answer 1

您将返回一个关联数组，因此请使用如下标识符：

$country_array[0]['name']

Answer 2

If it is object use the below code.

    echo $country_array[0]->name;

For array use

    echo $country_array[0]['name'];

Answer 3

You need to access the correct array index , in this case 0 .
Variables don't expand inside single-quotes , you need to use double-quotes and surround it with brackets {} (tks AbraCadaver ), ie:

echo "<p> {$country_array[0]['name']} </p>";
