getting dbase functions to work

Ok I am trying to use some of the PHP dbase functions and I get a call to undefined function error. Looking at the documentation I found a post on the site that said in order for these to work I need to compile PHP with dbase support with a command. Here is the explination You need to compile php with dbase support. `./configure --with-dbase ' will give you dbase support. Try `./configure --help' to get a list of modules and compile options. Geoff So my question is how can I compile php with this command? Will I have to get the source or is there some way that I can do this to my current version of php? Or would this command work when installing php? And how can I invoke this command when I do compile the source, say in Vis C++. Thanks, T P Cannell
