I am really interested in the comparison of PHP vs. the hundreds of templating engines used in other languages. PHP security issues (which may have been fixed in recent versions for all I know!) aside, is there anything that these modern frameworks can do that PHP cannot? If one argues by corporate authority as done elsewhere in this thread. Facebook used PHP, so clearly it scales (probably much better than Python). If anyone knows a resource (including books) that explores this topic in depth, I'd very much appreciate a link.
