This initiative was stated by a German researcher, Stefan Esser, on the 1st of March 2007. Esser was once a member of the PHP Security Response Team, but had since left the team in December 2006 due to un-cooperative and incompetent team members, according to his blog.

Also according to him, this initiative is not an attempt of revenge or payback, but rather an audit on PHP. The language came under scrutiny after he left, as PHP flaws had accounted to over 40 percent of the vulnerabilities reported in 2006.
