A new ORM Driver for mongoDB driver for PHP(PHP7)

require: PHP5.5+, MongoDB Driver.

Install

composer require rayful/db-manager2

History

https://github.com/rayful/DBManager

2.1版本

• 增加对日期的格式转换显示、还有入库时自动取当时时间的支持，见DatetimeUtility类；

$user = new stdClass();
$user->created = \rayful\MongoDB\DatetimeUtility::getNowDatetime();
echo \rayful\MongoDB\DatetimeUtility::toString($user->created);

• 增加对MongoGridFS的支持（依赖mongodb/mongodb包）

$gridFSManager = new \rayful\MongoDB\GridFSManager();
$id = $gridFSManager->upload('','abc.jpg', '/Users/kingmax/Downloads/全部行为.jpg');

$bytes = $gridFSManager->downloadBytes('', $id);

2.01版本

• Fix Bug, DataSet parseRequest()的强制参数类型去除
• Fix Bug, DBManager的insert、update、delete三个方法同时兼容数组及对象，并且入库前会将入参转换为数组，使代码执行稳定性更强（待验证）

2.0版本

• 去除几个函数，包括：DataSet=>setByRequest与readRequest，变成parseRequest($request);
• 分页依赖变成最新版rayful/pagination 2.0，留下paginate方法，但不包含样式，最新分页详细说明请见:https://github.com/rayful/Pagination
• 增加DBManager的批量操作功能，包括批量入库、更新及删除，请见DBManager内的三个方法，分别是insert、update、delete及flush方法。也可以见下面的例子。
• 魔术方法统一用_request_（开头）+请求变量名称。

Code Example:

define("MONGO_HOST", "mongodb://127.0.0.1");
define("MONGO_DB", "test");
