mysql
Closes a previously opened database connection.
Open non-persistent MySQL connections and result sets are automatically closed when their objects are destroyed. Explicitly closing open connections and freeing result sets is optional. However, it's a good idea to close the connection as soon as the script finishes performing all of its database operations, if it still has a lot of processing to do after getting the results.
