Chris argues that PHP scales well, because it fits into the Web's fundamental architecture. 'I think PHP scales well because Apache scales well because the Web scales well. PHP doesn't try to reinvent the wheel; it simply tries to fit into the existing paradigm, and this is the beauty of it.' (The article is also available on Chris' own website.)"
