Al número d'octubre de la revista php|architect hi ha un interessant article sobre PHP i IBM i (AS/400)
IBM and Zend have pushed hard to prove that PHP on the IBM i is a viable solution, and it is. While they tend to gear most of their marketing toward mainframe developers to switch over to PHP, coming to the IBM i from a PHPers experience is a whole different matter. We know the language, just not this well-aged platform. IBM has done their best to make developers welcome but the environment is still different. I'll go through some of the common annoyances of having to work on the i, as well as tips to make life easier. This is not an introduction to programming on the i, just tips to make your life easier. –by Chris Tankersley
