Cakephp with Sqlite3: How to connect to multiple sqlite file?

I working on a project where user register and get a free online shop using Cakephp v2.6.5. I'm using shared hosting so i can't create Mysql database for them, So I use sqlite instead. Because I need to use it with Moblie App too. In my code I dynamically create sqlite file for user after their register. But I don't know how to change database path in Cakephp. All I know is Cakephp use config in config/database.php file, but i can't init it dynamically.

In my config/database.php file:

public $sqliteDB = array(
    'datasource' => 'Database/Sqlite',
    'persistent' => false,
    //'database'=>'',
    'prefix' => '',
    'encoding' => 'utf8'
);

I trying to follow these link: CakePHP switch database (using same datasource) on the fly? and this link Cakephp can't change database on-the-fly

But I got nothing please help me for this case. Thank in advance.
