try {
$mongo = new MONGO ("MONGODB://USERNAME:PASSWORD@127.0.0.1:27017/DB1");

Print $e->getmessage ();
Exit
}

Select Database Blog

$user = Array (' name ' => ' Caleng ', ' City ' => ' Beijing ');
$collection->insert ($user);

modifying data

Copy Code code as follows:

$newdata = Array (' $set ' => Array ("City" => "Shanghai"));
$collection->update (Array ("name" => "Caleng"), $newdata);

Delete data

$collection->remove (Array (' name ' => ' Caleng '), Array ("Justone" => true);

Find data
Find a piece of data

Copy Code code as follows:

$result = $collection->findone (Array ("name" => "Caleng"));

Query a list

Find the data that was created longer than a certain time
$start = 1;
$counditionarray =array ("CTime" =>array (' $gt ' =>1337184000));
$list _data = $this->game_handle->find ($counditionarray);
$total = $this->game_handle->count ($counditionarray);
$list _data->limit ($count); Data End Position
$list _data->skip ($start); Where the data began to take place
Var_dump ($list _data);

In query

$collection->insert (Array ("category" => "veggie", "name" => "Corn"));
$collection->insert (Array ("category" => "veggie", "name" => "Broccoli"));
$keys = Array ("category" => 1);
$initial = Array ("Items" => array ());
$reduce = "function (obj, prev) {Prev.items.push (obj.name);}";

Echo Json_encode ($g [' retval ']);

Output results:

Copy Code code as follows:

[{"category": "Fruit", "items": ["apple", "peach", "banana"]},{"category": "Veggie", "Items": ["corn", "broccoli"]}]

Array
0 => Array ("category" => "fruit", "Items" =>array ("apple", "peach", "banana")),
1 => Array ("category" => "veggie", "Items" =>array ("corn", "broccoli"))
)
