How can one troubleshoot and debug PHP scripts that fail to display data after an external API has been updated or changed?

When PHP scripts fail to display data after an external API has been updated or changed, the issue could be due to compatibility issues with the new API version or changes in the data structure. To troubleshoot and debug this issue, you can start by checking the API documentation for any updates or changes that may affect your script. Additionally, you can use tools like Postman to test the API endpoints and verify the data being returned. Finally, you may need to update your PHP script to handle any changes in the API response format. 

// Sample PHP code snippet to troubleshoot and debug PHP scripts after an external API update

// Make a request to the API endpoint
$response = file_get_contents('https://api.example.com/data');

// Check if the response is empty or not in the expected format
if (!$response) {
    echo "Error: Unable to fetch data from the API";
} else {
    // Decode the JSON response
    $data = json_decode($response, true);

    // Check if the data is in the expected format
    if (json_last_error() !== JSON_ERROR_NONE) {
        echo "Error: Invalid data format received from the API";
    } else {
        // Display the data
        foreach ($data as $item) {
            echo $item['name'] . ": " . $item['value'] . "<br>";
        }
    }
}
