连接mongodb：

$mongoObj = new Mongo("127.0.0.1" , array(
                        ‘connect‘=>true,
                        ‘persist‘=>true
                    ));

选择库：

$mongoDB = $mongoObj->selectDB("wxdata");

选择集合:

$mongoColletion=$mongoDB->selectCollection("apachelog");

删除一个集合:

$mongoColletion->drop();

插入文档数据：

$mongoColletion->insert(array("firstname" => "Bob", "lastname" => "Jones" ));

修改更新文档数据：

$newdata = array(‘$set‘ => array("address" => "1 Smith Lane"));
$mongoColletion->update(array("firstname" => "Bob"), $newdata);

$mongoColletion->update(
        array("uri" => "/summer_pics"),
        array(‘$inc‘ => array("page hits" => 1)),
        array("upsert" => true)
    );

$mongoColletion->update(
        array("name" => "joe"),
        array("username" => "joe312", "createdAt" => new MongoDate()),
        array("upsert" => true)
    );

$today = array(‘$gt‘ => new MongoDate(), ‘$lt‘ => new MongoDate(strtotime("+1 day")));
$mongoColletion->update(
        array("birthday" => $today),
        array(‘$set‘ => array(‘gift‘ => $surprise)),
        array("multiple" => true)
    );

新增文档数据：

$obj = array(‘x‘ => 1);
$mongoColletion->save($obj);

$obj[‘foo‘] = ‘bar‘;
// $obj 不能被再次插入，导致 duplicate _id 错误
//$mongoColletion->insert($obj);
$mongoColletion->save($obj);

移除一个文档数据：

$mongoColletion->remove(array(‘httpstatus‘ => 200), array("justOne" => true));

统计文档数量：

$mongoColletion->count(array(‘httpstatus‘=>304));

查询一个文档：

$mongoColletion->findOne(array("httpstatus" => 200));

查看文档索引信息：

$mongoColletion->getIndexInfo();

构建文档索引：

// create an index on ‘httpstatus‘ ascending
$mongoColletion->ensureIndex(array(‘httpstatus‘ => 1));
// create a unique index on ‘size‘
$mongoColletion->ensureIndex(array(‘size‘ => 1), array(‘unique‘ => true));
// create a compound index on ‘size‘ ascending and ‘status‘ descending
$mongoColletion->ensureIndex(array(‘size‘ => 1, ‘status‘ => -1));

//全文索引
$mongoColletion->ensureIndex(
        array(
            ‘title‘ => ‘text‘,
            ‘desc‘ => ‘text‘,
        ),
        array(
            ‘name‘ => ‘ExampleTextIndex‘,
            ‘weights‘ => array(
                ‘title‘ => 100,
                ‘desc‘ => 30,
            )
        )
    );

关闭到mongodb的连接：

$mongoObj->close();

从php操作mongodb常用的函数就这么多了。
