mysqli_thread_id (PHP 5) mysqli_thread_id (no version information, might be only in CVS) mysqli->thread_id -- Returns the thread ID for the current connection DescriptionProcedural style: int mysqli_thread_id ( mysqli link ) Object oriented style (property): class mysqli { int thread_id }
The mysqli_thread_id() function returns the thread
ID for the current connection which can then be killed using the
mysqli_kill() function. If the connection is lost
and you reconnect with mysqli_ping(), the thread ID
will be other. Therefore you should get the thread ID only when you need it.
Замечание:
The thread ID is assigned on a connection-by-connection basis. Hence,
if the connection is broken and then re-established a new thread ID
will be assigned.
To kill a running query you can use the SQL command KILL QUERY processid.
