推荐答案

由于我们从未成功使Zend PHP以线程安全的方式运行，所以我们无法提供任何建议，除非有人为该端口创建Wordpress端口PH7，同时受G-WAN和线程安全支持.

As we never succeeded in making Zend PHP run in a thread-safe manner, there's no way we can advise, unless someone makes a Wordpress port for PH7, which is both supported by G-WAN and thread-safe.

由于现在多核系统已经成为规范(甚至在嵌入式平台上也是如此)，因此Zend最终将公开发布线程安全的PHP，或者人们将越来越多地寻求替代方案.

As multicore systems are now the norm (even on embedded platforms), either Zend will finally publicly release a thread-safe PHP, or people will increasingly look for alternatives.

根据"Nagi"的请求，这是发送的G-WAN PHP模块 向Zend进行审核:

Per the request of 'Nagi', here is the G-WAN PHP module sent to Zend for review:
