數(shù)據(jù)連接初始賬號密碼

賬號:admin

密碼:admin

首先我們建立一個文件:mongodb.php,設置需要連接賬號密碼,連接數(shù)據(jù)庫

$mongo_server_name = 'admin';
$mongo_server_pwd = 'admin';

// 連接Mongo數(shù)據(jù)庫 數(shù)據(jù)庫地址:端口/賬號:密碼;
$mongo = new Mongo('mongodb://localhost:27017/admin:admin');

// 選擇一個數(shù)據(jù)庫和要操作的集(如果沒有數(shù)據(jù)庫默認創(chuàng)建)
$collection = $mongo->selectDB('rrs_result')->selectCollection('content');

數(shù)據(jù)庫自動創(chuàng)建成功

添加一條數(shù)據(jù)!

結(jié)果:

更改數(shù)據(jù):

$set = array('title'=>'葉子');

$collection->update($where,array(

結(jié)果:

刪除數(shù)據(jù):

remove(array(

?>

結(jié)果:

No records is found.
