System.Data.SQLite

I tried to open a sqlite database generated by the system.data.sqlite in php using sqlite_open and versa vi, but it didn't work. The system.data.sqliteconnection tells me that the file generated by php isn't a sqlite database, and the php tels me the same thing about sqlite. What do I do? I realy need that to work. I thought that SQLite should work with SQLite in every platform. Please help. 

 Did you use a password with the database generated by the data provider? If so, it is encrypted and any other implementation of SQLite cannot read the files.

 No. I didn't.

You'll have to find out what version of SQLite PHP you have.  SQLite is backward compatible but not forward compatible.  It's likely the SQLite version in your PHP installation is older than the version of the engine in System.Data.SQLite.
