How can PHP developers handle errors or exceptions when opening a SQLite3 database?

When opening a SQLite3 database in PHP, developers can handle errors or exceptions by using try-catch blocks to catch any potential exceptions that may occur during the database connection process. This allows developers to gracefully handle any errors that may arise, such as connection failures or database file not found errors.

try {
    $db = new SQLite3('database.db');
    // Perform database operations here
} catch (Exception $e) {
    echo 'Error connecting to database: ' . $e->getMessage();
}
