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 --enable-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? Do I add this command to the php.ini file or is this done somewhere else? Thanks, T P Cannell
