                                  mysql_ping

   (PHP 4 >= 4.3.0)
   mysql_ping -- Ping a server connection or reconnect if there is no
   connection

Description

   bool mysql_ping ( [resource link_identifier])

   mysql_ping() checks whether or not the connection to the server is
   working. If it has gone down, an automatic reconnection is attempted.
   This function can be used by scripts that remain idle for a long
   while, to check whether or not the server has closed the connection
   and reconnect if necessary. mysql_ping() returns TRUE if the
   connection to the server is working, otherwise FALSE.

   See also mysql_thread_id() and mysql_list_processes().
