Since it's always good to know where we've come from (to see where we're headed, right?), Sebastian Bergmann has posted an observeration he's had upon PHP Magazin's look back at the world of PHP.
In his editorial for the 5 Year Anniversary Edition of the German PHP Magazin Björn Schotte posted a link to Kristian Köhntopp's wrapup of the world's first PHP conference which was held in October 2000 in Cologne, Germany.
The wrapup is of the PHP Congres Cologne that happened back at the beginning October of 2000. Topics disussed were PHPDocumentor, OpenTracker, using MySQL with PHP, web security, and much more. Check out the full posting for all of the details and a bit of a look back in PHP's history.
You can also check out some of Björn's comments about the article over on the ThinkPHP Blog.
