SQL Compact database with PHP

I have been given 2 files .DB and .sdf to work with. I have googled it a little and found out that its SQL Compact database format. I really have no idea how to work with these database files.

I have found here on stackoverflow some 3rd party too开发者_如何学Cls, bud they were all for windows (I am on Mac).

I have also tried to open it in SQLite but no success.

I need this data in my web app written in PHP. So conversion to MySQL or Postrge seems to be an ideal solution. Any ideas?

You can use MSSQL extension in PHP to work with these databases
