What are the recommended methods for error handling and feedback in PHP backup scripts to ensure successful execution and troubleshooting?

Issue: Error handling and feedback in PHP backup scripts are essential to ensure successful execution and troubleshooting. By implementing proper error handling techniques, such as try-catch blocks and logging errors, you can identify and resolve issues quickly. PHP Code Snippet: 

// Set error reporting level and display errors
error_reporting(E_ALL);
ini_set('display_errors', 1);

// Define a function for logging errors
function logError($message) {
    $errorLog = fopen('error.log', 'a');
    fwrite($errorLog, '[' . date('Y-m-d H:i:s') . '] ' . $message . PHP_EOL);
    fclose($errorLog);
}

// Example of using try-catch block for error handling
try {
    // Your backup script logic here
    // If an error occurs, throw an exception
    throw new Exception('Backup failed: Unable to connect to database');
} catch (Exception $e) {
    // Log the error message
    logError($e->getMessage());
    // Display a user-friendly error message
    echo 'An error occurred: ' . $e->getMessage();
}
