mysql_thread_id
(PHP 4 >= 4.3.0, PHP 5)
mysql_thread_id -- Return the current thread ID
Description
int
mysql_thread_id ( [resource link_identifier] )
Retrieves the current thread ID. If the connection is lost, and a reconnect
with mysql_ping() is executed, the thread ID will
change. This means only retrieve the thread ID when needed.
Parameters
-
link_identifier
The MySQL connection. If the
link identifier is not specified, the last link opened by
mysql_connect() is assumed. If no such link is found, it
will try to create one as if mysql_connect() was called
with no arguments. If by chance no connection is found or established, an
E_WARNING level warning is generated.
Return Values
The thread ID on success, or FALSE on failure.
