ice_berg16(寻梦的稻草人) 我铁一端文字，你到http://www.zend.com/apidoc/自己看看。"Extending PHP" is easier said than done. PHP has evolved to a full-fledged tool consisting of a few megabytes of source code, and to hack a system like this quite a few things have to be learned and considered. When structuring this chapter, we finally decided on the "learn by doing" approach. This is not the most scientific and professional approach, but the method that's the most fun and gives the best end results. In the following sections, you'll learn quickly how to get the most basic extensions to work almost instantly. After that, you'll learn about Zend's advanced API functionality. The alternative would have been to try to impart the functionality, design, tips, tricks, etc. as a whole, all at once, thus giving a complete look at the big picture before doing anything practical. Although this is the "better" method, as no dirty hacks have to be made, it can be very frustrating as well as energy- and time-consuming, which is why we've decided on the direct approach.Note that even though this chapter tries to impart as much knowledge as possible about the inner workings of PHP, it's impossible to really give a complete guide to extending PHP that works 100% of the time in all cases. PHP is such a huge and complex package that its inner workings can only be understood if you make yourself familiar with it by practicing, so we encourage you to work with the source.我是菜鸟，以后咄咄指点！
加密后的文件->zendcatch->php解释器
加密前的文件->php解释器
产生的结果肯定是相同的，我看过zend的文档，根据他们的资料你自己也能扩展php，甚至做一个自己的加密php文件的解释器！我说的都是废话！没什么实际用处，不好意思了！^-^
自己怎么扩展ＰＨＰ呢，请yuezw()笨笨的菜鸟() 指点一二！
