According to this report, Zend has received "a $20 million boost through a fourth round of funding." According to Zend's own press release:
The new funds will enable us to expand faster in emerging geographical markets, accelerate our product development and extend the services organization to meet the demands of our growing number of enterprise PHP customers.
With the attrition Zend has suffered this past year, it's nice to see some positive news. Many people associate Zend with PHP's commercial presence, so a strong Zend is good for all of us.
