用一个函数解决ThinkPHP 连接 MySQL与 MongoDB，请注意M函数
1. config.php设置 //.配置MySQL数据库<br>
'DB_MYSQL' => array(<br>
'db_type'=>'mysqli',<br>
'db_user'=>'用户名',<br>
'db_pwd'=>'密码',<br>
'db_host'=>'127.0.0.1',<br>
'db_port'=>'3306',<br>
'db_name'=>'数据库名',<br>
'db_charset'=>'utf8',<br>
),<br>
<br>
//.配置MongoDB数据库<br>
'DB_MONGO' => array(<br>
'db_type'=>'mongo',<br>
'db_user'=>'用户名',<br>
'db_pwd'=>'密码',<br>
'db_host'=>'localhost',<br>
'db_port'=>'27017',<br>
'db_name'=>'数据库名',<br>
),2. 写一个M函数，实现数据库的调用 //. 调用MONGO和MYSQL数据库<br>
protected function M( $table_name = '', $db_type = 'DB_MYSQL' ){<br>
<br>
$db_config = C($db_type);<br>
$db_prefix = C('DB_PREFIX');<br>
<br>
if( $table_name == '' ){ return false; }<br>
<br>
if( $db_type == 'DB_MYSQL' ){<br>
return M( $table_name , $db_prefix , $db_config );<br>
}else if( $db_type == 'DB_MONGO' ){<br>
return M( '\Think\Model\MongoModel:' . $table_name , $db_prefix , $db_config );<br>
}else{<br>
return false;<br>
}<br>
<br>
}//;3. 调用M函数的实例 //. 调用自定义的M函数<br>
<br>
//. 连接MySQL数据库<br>
echo 'Mysql:';<br>
$list = $this->M('user','DB_MYSQL')->select();<br>
dump( $list );<br>
<br>
//. 连接MongoDB数据库<br>
echo 'Mongo:';<br>
$list = $this->M('user','DB_MONGO')->select();<br>
dump( $list );希望对您有所帮助！！！
