Making a Connection
To connect to the database server, use one of the following:
<?php$connection = new MongoClient(); // connects to localhost:27017$connection = new MongoClient( "mongodb://example.com" ); // connect to a remote host (default port: 27017)$connection = new MongoClient( "mongodb://example.com:65432" ); // connect to a remote host at a given port?>
You do not have to explicitly disconnect from the database. The driver uses persistent connections and will re-use already established connections.
