if you are using persistent connections (p:hostname) and after some idle time mysqld has closed the connection you lose the MYSQLI_OPT_INT_AND_FLOAT_NATIVE setting due the automatic reconnect

when the application is written with declare(strict_types=1); and used mysqli_options($conn, MYSQLI_OPT_INT_AND_FLOAT_NATIVE, true) any typesafe comparison based on database rows then fails

this is really serious and make persistent connections dangerous to useless

noticed this recently after a benchmark worked fine with 9000 requests/second and later random requests depending if the application chosed the readonly-slave or the master things started to break
