Erorr codeigniter上的多个数据库

Question

我想建立一个项目使用多个数据库我在项目中使用3个数据库，有时应用程序正常运行，但突然间有关于什么数据库错误的警告错误？

Filename: C:/xampp/htdocs/sbc-portal/system/database/DB_driver.php 

Line Number: 436 

Answer 1

二级数据库添加以下代码

$db['otherdb']['hostname'] = "localhost"; 
$db['otherdb']['username'] = "root"; 
$db['otherdb']['password'] = ""; 
$db['otherdb']['database'] = "other_database_name"; 
$db['otherdb']['dbdriver'] = "mysql"; 
$db['otherdb']['dbprefix'] = ""; 
$db['otherdb']['pconnect'] = FALSE; 
$db['otherdb']['db_debug'] = FALSE; 
$db['otherdb']['cache_on'] = FALSE; 
$db['otherdb']['cachedir'] = ""; 
$db['otherdb']['char_set'] = "utf8"; 
$db['otherdb']['dbcollat'] = "utf8_general_ci"; 
$db['otherdb']['swap_pre'] = ""; 
$db['otherdb']['autoinit'] = TRUE; 
$db['otherdb']['stricton'] = FALSE; 

然后连接到辅助数据库

$otherdb = $this->load->database('otherdb', TRUE); 
$test= $otherdb->get('test'); 

希望工程。
