How can PHP developers ensure efficient error handling and debugging when using functions like get_headers?

When using functions like get_headers in PHP, developers can ensure efficient error handling and debugging by checking for errors and handling exceptions properly. This can be done by using try-catch blocks to catch any exceptions that may occur and using error handling functions like error_log or trigger_error to log or display error messages. 

$url = 'https://www.example.com';
$headers = @get_headers($url);

if ($headers === false) {
    error_log('Error fetching headers for ' . $url);
} else {
    foreach ($headers as $header) {
        echo $header . "<br>";
    }
}
