When dealing with PHP errors related to failed HTTP requests and external entity loading, what best practices should be followed to identify and resolve the underlying issues effectively?

When dealing with PHP errors related to failed HTTP requests and external entity loading, it is important to check for error messages or logs to identify the underlying issues. Common causes could include network connectivity problems, incorrect URLs, or server-side errors. To resolve these issues effectively, ensure that the URLs are correct, check for any network/firewall restrictions, and handle errors gracefully in your code. 

<?php

$url = 'https://example.com/api/data';
$response = file_get_contents($url);

if ($response === false) {
    // Handle the error gracefully
    echo 'Failed to load data from API';
} else {
    // Process the response data
    echo $response;
}

?>
