Description:
------------
I use mysqli::ping() to test whether MySQL connection is still alive (scripts waits long before using MySQL again).

On FALSE, it also sends E_NOTICE which is not (IMO) appropriate, since function returns TRUE/FALSE on success/failure.

Expected result:
----------------
I expect mysqli::ping() just to return TRUE/FALSE.

When I use $variable without initialisation, I get E_NOTICE and so if I want to avoid getting E_NOTICE, I use isset($variable) before using $variable itself.

I expected same behaviour from mysqli::ping() - just let me know if connection is dead or alive and do not mess with my logs too, it is redundant without advantage.

Actual result:
--------------
mysqli::ping() returns TRUE/FALSE, but it also sends E_NOTICE "mysqli::ping(): send of 5 bytes failed with errno=32 Broken pipe".
