如何在codeigniter中集成mongodb库以与mongodb建立数据库连接 [英] how to integrate mongodb library in codeigniter for database connection with mongodb
问题描述
我正在使用codeigniter和mongodb数据库创建应用程序。由于codeigniter不包含mongodbs驱动程序,因此我使用了内置库来连接mongodb。我已使用此链接来创建mongodb配置文件和Mongo_db库。
配置文件类似于application isconfig\mongodb:
I am creating application with codeigniter and mongodb database. As codeigniter doesn't contain mongodbs driver, I have used built in library to connect with mongodb. I have used this link to create mongodb configration file and Mongo_db library. The configration file is like application\config\mongodb:
<?php
$config['default']['mongo_hostbase'] = 'localhost:27017';
$config['default']['mongo_database'] = 'test';
$config['default']['mongo_username'] = '';
$config['default']['mongo_password'] = '';
$config['default']['mongo_persist'] = FALSE;
$config['default']['mongo_persist_key'] = 'ci_persist';
$config['default']['mongo_replica_set'] = FALSE;
$config['default']['mongo_query_safety'] = 'safe';
$config['default']['mongo_suppress_connect_error'] = FALSE;
$config['default']['mongo_host_db_flag'] = FALSE;
?>
和Mongo_db库就像:
and Mongo_db library is like:
<?php if ( ! defined('BASEPATH')) exit('No direct script access allowed');
class Mongo_db
{
public function __construct()
{
//Check mongodb is installed in your server otherwise display an error
if ( ! class_exists('Mongo'))
{
$this->_show_error('The MongoDB PECL extension has not been installed or enabled', 500);
}
//get instance of CI class
if (function_exists('get_instance'))
{
$this->_ci = get_instance();
}
else
{
$this->_ci = NULL;
}
//load the config file which we have created in 'config' directory
$this->_ci->load->config('mongodb');
$config='default';
// Fetch Mongo server and database configuration from config file which we have created in 'config' directory
$config_data = $this->_ci->config->item($config);
try{
//connect to the mongodb server
$this->mb = new Mongo('mongodb://'.$config_data['mongo_hostbase']);
//select the mongodb database
$this->db=$this->mb->selectDB($config_data['mongo_database']);
}
catch (MongoConnectionException $exception)
{
//if mongodb is not connect, then display the error
show_error('Unable to connect to Database', 500);
}
}
?>
当我运行应用程序时,它给我一个像
的错误遇到了
您的application / config / mongodb.php文件似乎不包含有效的配置数组。
When I run the application it give me an error like An Error Was Encountered Your application/config/mongodb.php file does not appear to contain a valid configuration array.
有人可以告诉如何解决此错误并建立与mongodb的连接吗?
can anybody tell How to resolve this error and setup connection with mongodb?
