    | mysql_thread_id    (PHP 4 >= 4.3.0, PHP 5) mysql_thread_id -- Return the current thread IDDescriptionint 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_identifierThe 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.
