There are still many around - most of them die because admins give up or users leave - if you actually miss them it should be easy to find some for your interests
I would love to have some directory with all kinds of active (PHP) web forums. That was the heyday of the open web for me.
Do you have any tips on how to specifically search for these forums? Without just googling for topics and browsing hours to find some. When I think about it, just googling/searching might be the only way.
I miss the old skool php web forums.
