Also, as others have commented, the PDO exception mode is also ignored. The warning is sent to php://stdout no matter what, even if making sure the PDO instance is destroyed and disconnected. Apparently, the warning is sent to php://stdout during garbage collection. It makes JSONRPC servers and other stuff impossible to use. ------------------------------------------------------------------------ [2015-01-20 03:10:06] nospampls at nospam dot org I have the same problem, regardless PDO::ERRMODE_EXCEPTION I sometimes get warnings or both warnings and the pdoexception equivalent at the same time (!!!). please fix ------------------------------------------------------------------------ [2013-05-03 05:09:30] fog at yandex dot ru There is another similar problem, sometimes connection fails with message: Warning: PDO::__construct(): MySQL server has gone away in [...file_path...] on line N It happens despiting that PDO::ATTR_ERRMODE is set to PDO::ERRMODE_EXCEPTION ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
