Description:
------------
As the Php Reference said:

SQLite3::open

Returns TRUE on success, FALSE on failure to open the database.

But this IS NOT TRUE.

It Returns NULL.

Test script:
---------------
class testSQLite3 extends SQLite3{
     
    public function __construct(){
        var_dump( $this->open('test.sqlite3') );
    }
     
}
 
new testSQLite3();

Expected result:
----------------
//Create File 'test.sqlite3' And
//output
//bool(true)


Actual result:
--------------
//Create File 'test.sqlite3' And
//output
//NULL
