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 error is generated.
Return Values
The thread ID on success, or FALSE on failure.
Examples
Example #1 mysql_thread_id() example
<?php $link = mysql_connect('localhost', 'mysql_user', 'mysql_password'); $thread_id = mysql_thread_id($link); if ($thread_id){ printf("current thread id is %d\n", $thread_id); } ?>
The above example will output
something similar to:
Load balance : Server 04
