Since many of the people who might be interested in FX might not be familiar with PHP -- or the XML support in FileMaker for that matter -- here are some links which may be helpful:

Longterm Solutions
Longterm Solutions provides consulting for and hosting of both straight FileMaker and Web-enabled FileMaker solutions. Whichever you need, give them a shout and they'll lend you a hand.
Soliant Consulting
Steve Lane of Soliant Consulting is one of the best with PHP in the FileMaker community, and also contributed the awesome object-based error handling that is now part of FX.php™. The folks from Soliant have also written a book that covers FX.php™. You'll find a link on my books page.

About.com's FileMaker Page
The FileMaker page at About.com has links to some very useful information for FileMaker developers (Development Standards, info on Complex Calculations, etc.) The amount of information on this page will only increase, so stop back ocasionally to see what's new.

The PHP On-Line Manual
This is the English version of PHP's official on-line documentation (versions in other languages are linked from this page.) It's very good. There are even user submitted tips, clarifications, etc. If you're new to PHP, or thinking of starting with it, check out this site.

Point in Space
Looking for someone to host your FileMaker solution powered by FX.php™? Point is Space has been hosting FileMaker solutions powered by Lasso for some time, and these days they're hosting FX.php™ based sites as well. If you're working with FX.php™ and you need someone to take care of the hosting for you, head over to their site.

Let 'em know you heard about them here.

FileMaker's XML Central
This was the home for information about XML and FileMaker. It was really quite good. Unfortunately it's moved, and finding things on FileMaker's web site tends to be rather frustrating. I would like to relink this page if it's still out there.

Home Page of Gjermund Gusland Thorsen
Gjermund deserves a heaping portion of kudos for his help with FX! He has given numerous suggestions and requests to help FX along, as well as doing what must have been a lot of legwork to put the extended character tables together. Not to mention his interest in creating FX add-ons for popular WYSIWYG HTML editors. (Gjermund also deserves some praise for his patience while waiting for me to update everything...=)

Home Page of Marc Liyanage
Just who is Marc Liyanage and why should you care? Well, though I don't know him personally, I DO know that if you're hoping to get certain nifty Unix tools (like PHP and MySQL, for example) running under Mac OS X, Marc has done a lot of the hard work for you. Just have a look at the software portion of his web site. (Link added with the permission of the site's owner.)

JpGraph
How does a PHP class sound that draws about any kind of graph that you could want? Now suppose that class spanned the gamut from easy setup for basic data sets to powerful handling of complex data, does that sound interesting? If so, check out JpGraph.

Submit Your FX.php™ Site
The reception for FX has been awesome! A lot of you out there are probably already using FX. Have you used FX.php™ to serve your FileMaker Pro data on the web? Would you like to show your work off? Drop me a line, and you may just find your site THE LIST! Granted, I do have final say over who I link to from my site, but I'll post as many as I can.
