Error message:
Warning: dbase_open () [function. dbase-open]: unable to open database test. dbf in F: \ web \ AppServ \ www \ test \ dbf. php on line 3

I tried many paths with the same warning: (the path is correct)
$ File_dbf = 'Test. dbf ';
$ File_dbf = '/test. dbf ';
$ File_dbf =./test. dbf ';
$ File_dbf = 'http: // localhost/test. dbf ';
$ File_dbf = 'F: \ web \ AppServ \ www \ test. dbf ';
$ File_dbf = 'F:/web/AppServ/www/test. dbf ';

What is the reason? What should we do? Thank you ~
