Disable PHP Warning

I'm getting PHP Warning:

PHP Warning:  Error while sending QUERY packet. PID=23374 in vendor/legow/reconnecting-pdo/src/ReconnectingPDO.php on line 325
PHP Stack trace:
PHP   1. {main}() src/worker/db_test.php:0
PHP   2. Doctrine\DBAL\Connection->ping() src/worker/db_test.php:46

PHP   7. PDO->query() vendor/legow/reconnecting-pdo/src/ReconnectingPDO.php:325

I've tried to catch it with set_error_handler with no luck.

So, let's mute it by adding @: @$this->connection->query('SELECT 1');

@adamturcsan can you approve, please?

Sorry for the late response.
Could you please describe the environment and the context of the phenomena?
I'd like to recommend using Exception style error handling (https://www.php.net/manual/en/pdo.error-handling.php) instead. Not just because then it should throw a warning but because that's the base of the reconnecting mechanism. It should be set analogous to the original PDO.

Does it solve your problem?

Sorry, but I'm not exactly a fan of the @ style solutions, so I'd like to understand the issue first.

Thanks for your feedback!

I'm using PDO::ATTR_ERRMODE => PDO::ERRMODE_EXCEPTION, but it isn't helping.
It's a bug in PDO that causes both warning and exception to be triggered.
You can find a more detailed explanation here: PDO::ERRMODE_EXCEPTION doesn't suppress warning
So, as much as I hate using @, I couldn't find any better solution.
Currently, I ended up extending your class and overriding the ping method, which is also not a great solution, because if you will update your ping method - I will have to update my method as well.
