Facebook PHP Source Code from August 2007

README.md

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:

http://techcrunch.com/2007/08/11/facebook-source-code-leaked/

It became a big deal:

http://www.techmeme.com/070812/p1#a070812p1

The two files are index.php (the homepage) and search.php (the search page)

I don't know what ended up happening to the guy who stole the code.

I found these files today while searching for another Facebook related file. Worth preserving as part of Internet history.

This is a good piece of Internet history, and has some of the only leaked chunks of the original 2003 code that Mark Zuckerberg originally wrote in his dorm room at Harvard. There's another "original" Facebook code on GitHub (although, not on Gist) published by "megaloglobal" that purports to be the "original 2003 version", whilst that emulates 2008-era Facebook, the one that succeeded this version of the platform here and created the code used until like 2012.
