NYCPHP Meetup

[Jake McGraw]

I believe it was my Uncle Ben who once said "With great power comes great
responsibility." PHP does things in a manner different than C or Java or
Python or etc etc etc (that is why it is called PHP). There are features
that some programmers believe are shortcomings, there are shortcomings that
some programmers believe are features. Know the language and its quirks and
you'll never get bitten, program with some "responsibility".
