stop using "try ... catch" operators

stop using "try ... catch" operators,
see https://phpdelusions.net/top#try_catch

Catching an exception only to report it is a sure overkill. Simply because uncaught exception is a fatal error already, and it will be reported by itself. Without that blunt try/catch/die sequence, making your code much cleaner.

Important! You don't have to check the result of execute() (as it is often shown in low-quality tutorials). Such a condition will make no sense, as in case of error, a PDOException will be thrown and the script execution will be terminated, which means such a condition will never reach the else part.
Neither a try ... catch operator should be used, unless you have a specific scenario to handle the error, such as a transaction rollback shown below. Please see the article about error reporting for the details.
