With all that's been said in this thread, and all that has been observed
(i.e. a large number of PHP vulnerabilities--please don't try and defend
this; the common thing that everyone agrees on is that PHP tries to
cater to all users (not necessarily programmers, which can make it
insecure), I'm going to ask two questions:

1.) If I have to write PHP, how do I write secure PHP? Give me a number
of ensures that I can follow and check-mark each and live a happy
life--for the most part.

2.) From a security standpoint what is a better, open-source replacement
to PHP?
