No our tools are Windows client tools so they won't work on Linux and PHP.
Sounds to me you either need to:
As Jim pointed out you can use ODBC to connect to FoxPro data I believe with an ODBC driver, although I'm not sure what availability there is for that on Linux. This will work as long as you can somehow map the remote machine/folder.
This would involve setting up some sort of service (Web Service, REST Service) that you could call from PHP to retrieve data indirectly from the remote database. How this would be implemented depends on what platform the data resides and what tools you want to use to publish/share the data. Web Connection is our Windows server tool that can help with this. We have a remote XML data interface we provide as part of Web Connection that could make this work fairly easily as long as your PHP code has the abililty to parse XML data.
Hope this helps,
