PHP-X开发扩展

extension->info(

return extension;
}

这个是根据PHP-X中的cpp_ext这个demo改的。只实现了一个功能，就是拦截PHP编译时的opcode。

拦截opcode有什么作用？可以做加密扩展也可以做opcode反编译。

之前有用过PHPCPP，功能也不错，但是用到PHP内置API的时候不太方便，这个PHP-X确实挺方便，而且也挺小。

其他的话，两个框架还是比较相似的。

配置环境中可能会出现一个问题，就是无法加载libphpx.so，这个是因为这个库没有被加载到全局lib库后没有更新缓存，所以会提示这个错误。只需要执行下面命令即可

/sbin/ldconfig –v
