In the context of PHP development, what strategies can be employed to improve error handling and debugging for issues like failed database operations or incorrect data manipulation?

To improve error handling and debugging for issues like failed database operations or incorrect data manipulation in PHP development, developers can use try-catch blocks to catch exceptions, log errors to a file or database for later analysis, and implement proper error messages to provide feedback to users or administrators.

try {
    // Database operation code here
} catch (Exception $e) {
    // Log the error to a file or database
    error_log('Database error: ' . $e->getMessage());
    // Display a user-friendly error message
    echo 'An error occurred while processing your request. Please try again later.';
}
