How can exceptions be effectively utilized for handling errors in parsing and validating opening hours input in PHP?

When parsing and validating opening hours input in PHP, exceptions can be effectively utilized to handle errors. By throwing exceptions when encountering invalid input or errors during parsing, we can gracefully handle these situations and provide informative error messages to the user. 

try {
    // Parse and validate opening hours input
    // If input is invalid, throw an exception
    if (!isValidOpeningHours($input)) {
        throw new Exception('Invalid opening hours format');
    }

    // Process the valid opening hours input
    processOpeningHours($input);

} catch (Exception $e) {
    // Handle the exception by displaying an error message to the user
    echo 'Error: ' . $e->getMessage();
}

// Function to validate opening hours input
function isValidOpeningHours($input) {
    // Validation logic here
}

// Function to process opening hours input
function processOpeningHours($input) {
    // Processing logic here
}
