Web Form Processing

[#1]

Further to my post about preventing bot etc from harvesting email addresses from web sites I have to say I'm very disappointed that Plusnet don't provide form processing.
Is there any particular reason for it?

Probably due to the number of possible options of what people may want to do and the amount of information already available on the net.
e.g.  PHP Form Processing

Web sites on Homepages are intended to be static. The email form and hit counter scripts provide limited dynamic capability. If you need more than that for a guest book, etc the ccgi server with PHP, Perl and (a very dated version of) MySQL provides it.

Is there anywhere where I could get guidance as to how I use those please. I'm not very geekish on this sort of thing. Although I like using HTML I still want to keep it fairly simple. I've Googled PHP but can't disseminate much about it.
Thanks.

The link in the following quote from my post in your MySQL thread provides an outline of the language including examples that work.
