In one of their latest postings, PHP Magazine talks about the popularity that PHP is (still) gaining among hosting providers.

With the cost of Web access and Web accounts going south and issues with the quality of service constantly resurfacing, VARs are touting PHP for dynamic Web pages. In a new article that focuses on Web hosting, CRN takes a look at why solution providers and vendors alike are so excited about PHP. Matt Villano, the author, goes onto say, "With more than 15 million Web sites running PHP, the language is the hottest thing to hit hosting since AOL. Customers are clamoring for it, and solution providers are selling PHP-based services in droves. As a result, vendors like Alabanza and Zend Technologies are launching new channel efforts designed to help partners make PHP a top seller."

The link to the actual article provides a bit more depth, talking about the well-developed nature of quite a few "business products" written in PHP as well as a mention of the new Zend product - the Turbo PHP accelerator.
