From a pointer over on PHP Magazine's site:

Marcus Whitney, our "PHP 5 Tried For You" columnist, has a new post on his blog about some of the recent interviews that he did with Tech Heads at SugarCRM, PriceGrabber and United Press International about Enterprise PHP Development. "One of the amazing things that's happened is that I fulfilled the task of interviewing head programmers at three major information technology companies utilizing PHP in enterprise development and centering there efforts on PHP 5. Zend is going to do a webcast where you can see and hear them all, which I would recommend, and I had the pleasure of interviewing them all for PHP Solutions. Really interesting stuff.

Jacob Taylor, Vice President of Engineering at SugarCRM has lead a team that has literally worked wonders in the last year. Have you seen their site lately? Better yet their app or their diverse business model? It's amazing to think that a virtual start-up can support that kind of product offering within their first year of operations. They are so pumped about PHP 5 and what it means to the speed and strength of their development cycles." Read on...

It's always good to see companies stepping forward and saying "we use PHP, and here's all the cool stuff we're using it for". People are still wondering these days "is PHP ready for the enterprise" and I think, without a doubt, the answer is a resounding "yes!".
