Growing up with PHP

I've now been using PHP for over 12 years, and over that time I've learnt a lot of lessons, many of them the hard way, about building good web applications that scale, and some of the relatively easy and cheap things you can do to avoid pain later on. This talk was presented at the PHP UK Conference pre-event social, and covers a lot of the technologies and techniques that would be discussed in more depth at the conference itself.
