The Zend Developer Zone has an announcement about an upcoming PHP user group meeting happening in Boston:
What is less known is that PHP is also making significant inroads in the enterprise. Join BostonPHP, IBM and Zend as we discuss where Enterprise PHP (and OSS) is going and how it's going to get there. This promises to be a great evening with plenty of “horsepower” to answer your questions.
Speakers for the evening will be Mark de Visser, Zend's CMO and David Boloker, IBM's CTO of Emerging Internet Technologies. The meeting will be happening on Tuesday, September 11th starting at around 6:30pm. The meeting will be held in Cambridge at 1 Rodger's Street. Check out the official announcement of the meeting for full details.
