IIS+PHP+mysql的最佳选择，这是Zend官方推出的一个免费软件，让你的IIS一键安装PHP环境。ZEND官方说，可以让你的PHP运行在WIN环境下，像LINUX环境一样的稳定。
Zend Core is a certified PHP distribution that includes the most reliable and up-to-date version of PHP, tested PHP extensions, database drivers and other enhancements. Zend Core is bundled with Zend Framework (the leading open-source PHP framework), Apache and MySQL and IBM DB2 Express-C databases. The complete stack is built, tested and benchmarked to ensure optimum reliability and performance for multiple platforms.
Zend Core makes it easy to have consistent environments for each stage of the PHP application lifecycle, avoiding application errors that often go undiscovered during development, testing and staging because of subtle differences between these environments.
