I came across a post on slashdot that PHP installs with easter eggs.

The E-Eggs are listed on Chris Shifflett’s blog.

Chris suggests that they are a good trick for finding out if sites are using PHP, perhaps sites that might want to hide that for some reason like the creator of Ruby on Rails, 37signals.com.

I tried this on the RubyOnRails.org site, no luck.

Here is one from this server:  http://tiredrobot.com/?=PHPE9568F35-D428-11d2-A769-00AA001ACF42

On the same slashdot post, a post also stated that the following big name sites all used PHP:

Disney, IBM, AT&T, MTV

I’m off to test out the eggs….
