The bottom of the frame must still use the PDO bar, give the configuration file, just to facilitate your use

The frame layer is then combined into a DSN connection string for PDO

PHP7 has started to unify the use of PDO to connect to MySQL database

home/conf/config.php under the module under the thinkphp file

Load the following

Database configuration

'DB_TYPE'  =>'mysql','DB_HOST'  =>'localhost','DB_PORT'  =>'3306','DB_NAME'  =>'数据库名称','DB_USER'  =>'数据库用户名','DB_PWD'   =>'数据库密码','DB_CHARSET'=>'utf8',
