How can one effectively troubleshoot issues with extracting technical details from the Amazon API in PHP?

Issue: When extracting technical details from the Amazon API in PHP, ensure that you are using the correct endpoint, passing the required parameters, and handling the response properly. 

// Example code snippet for extracting technical details from the Amazon API in PHP

// Set up the request parameters
$access_key = 'YOUR_ACCESS_KEY';
$secret_key = 'YOUR_SECRET_KEY';
$associate_tag = 'YOUR_ASSOCIATE_TAG';
$base_url = 'https://webservices.amazon.com/onca/xml';

$params = array(
    'Service' => 'AWSECommerceService',
    'Operation' => 'ItemLookup',
    'AWSAccessKeyId' => $access_key,
    'AssociateTag' => $associate_tag,
    'ItemId' => 'B01M1JVL3X',
    'ResponseGroup' => 'ItemAttributes',
);

// Generate the request signature
ksort($params);
$canonical_query_string = http_build_query($params);
$string_to_sign = "GET\nwebservices.amazon.com\n/onca/xml\n" . $canonical_query_string;
$signature = base64_encode(hash_hmac('sha256', $string_to_sign, $secret_key, true));
$signature = rawurlencode($signature);

// Make the API request
$request_url = $base_url . '?' . $canonical_query_string . '&Signature=' . $signature;
$response = file_get_contents($request_url);

// Parse the API response
$xml = simplexml_load_string($response);
$technical_details = $xml->Items->Item->ItemAttributes;

// Output the technical details
print_r($technical_details);
