How can exceptions be used effectively in PHP to handle errors and provide a full stack trace?

To effectively handle errors and provide a full stack trace in PHP, you can use exceptions. By throwing exceptions when an error occurs, you can catch and handle them in a centralized location, allowing for better error management and logging. To include a full stack trace in the exception message, you can use the `getTraceAsString()` method within the exception constructor. 

try {
    // Code that may throw an exception
    throw new Exception('An error occurred.');
} catch (Exception $e) {
    echo 'Caught exception: ' . $e->getMessage() . PHP_EOL;
    echo 'Stack trace: ' . $e->getTraceAsString();
}
