Class: PMO_MyDbms

static PMO_Dbms factory( [ $object = NULL])

returns a reference to the PMO_Dbms object If it does not already exists a new object is created and retained for future use

if an PDO object is provided as parameter, it will be used and will replace any existing instance.

This uses the singleton design pattern. To get the object, use code such as this:

1.  // either returns an existing instance or creates a new one and returns it
2.  $db = PMO_MyDbms::factory();
3.  
4.  // use an already defined PDO instance
5.  $pdo = new PDO("sqlite:/hoem/user/db/mydatabase.db");
6.  $db = PMO_MyBbms::factory($pdo);
