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.
