What role do exceptions play in handling errors and improving code structure in PHP applications?

Exceptions play a crucial role in handling errors in PHP applications by allowing developers to gracefully handle unexpected situations and prevent the application from crashing. They also help improve code structure by separating error-handling logic from the main application logic, making the code more maintainable and readable. 

try {
    // Code that may throw an exception
    if ($condition) {
        throw new Exception('An error occurred');
    }
} catch (Exception $e) {
    // Handle the exception
    echo 'Error: ' . $e->getMessage();
}
