1. config.php設(shè)置
//.配置MySQL數(shù)據(jù)庫(kù)
'DB_MYSQL' => array(
'db_type'=>'mysqli',
'db_user'=>'用戶名',
'db_pwd'=>'密碼',
'db_host'=>'127.0.0.1',

'db_host'=>'localhost',

2. 寫一個(gè)M函數(shù)，實(shí)現(xiàn)數(shù)據(jù)庫(kù)的調(diào)用
//. 調(diào)用MONGO和MYSQL數(shù)據(jù)庫(kù)
protected function M( $table_name = '', $db_type = 'DB_MYSQL' ){

$db_config = C($db_type);
$db_prefix = C('DB_PREFIX');

if( $table_name == '' ){ return false; }
if( $db_type == 'DB_MYSQL' ){
return M( $table_name , $db_prefix , $db_config );
}else if( $db_type == 'DB_MONGO' ){
return M( '\Think\Model\MongoModel:' . $table_name , $db_prefix , $db_config );
}else{
return false;
}
}//;
復(fù)制代碼
3. 調(diào)用M函數(shù)的實(shí)例
//. 調(diào)用自定義的M函數(shù)
//. 連接MySQL數(shù)據(jù)庫(kù)
echo 'Mysql:';
$list = $this->M('user','DB_MYSQL')->select();
dump( $list );
//. 連接MongoDB數(shù)據(jù)庫(kù)
echo 'Mongo:';
$list = $this->M('user','DB_MONGO')->select();
dump( $list );
