//The default port 27017 is used to connect to the local machine. Of course, you can also connect to a remote host such as 192.168.0.4:27017. If the port is 27017, the port Can be omitted

$m = new Mongo();

//Select comedy database. If the database has not been created before, it will be automatically created. You can also use $m->selectDB(“comedy”);

$collection->insert($obj);

//Query all records

$cursor = $collection->find();

//Traverse the documents in all collections

foreach ($cursor as $obj)

{

echo $obj[“title”] . “\n”;

}

//Delete all data

$collection->remove();

//Delete name as hm

$collection->remove(array('name'=>'hm'));

//Disconnect MongoDB
