Mongo::close
(PECL mongo >=0.9.0)
Mongo::close — Closes this connection
Description
This method does not need to be called, except in unusual circumstances. The driver will cleanly close the database connection when this Mongo instance goes out of scope.
If objects do not go out of scope between requests, you may wish to call this method at the end of your program to keep old connections from hanging around. However, it is probably more efficient use a persistent connection, which will automatically create a connection if needed and use it for as many requests as possible.
If you are connected to a replica set, close() will only close the connection to the primary.
Parameters
This function has no parameters.
Return Values
Returns if the connection was successfully closed.
