安装 Phalcon 也极其简单，只需要下载一个文件（php_phalcon.dll），
要以 phpinfo() 里面逗Architecture地属性为准！
把php_phalcon.dll 解压出来放在 {WampServer安装目录}/bin/PHP/php5.4/ext 目录下面，然后修改php.ini文件，PHP.ini配置文件增加参数逗extension=php_phalcon.dll地，
然后重启 Apache 服务就好了，重启后用phpinfo查看是否安装成功。
如果服务器报 500 internal server error，一般就是 Phalcon 版本和环境不统一。
比如逗Phalcon 1.1.0 - Windows x86 for PHP 5.4.0 NTS (VC9)地，就是给32位系统（x86）用的，对应的PHP版本是5.4.0（只要是5.4就可以，比如5.4.1也行）。
NTS是非线性安全的，如果你的phpinfo()显示逗Thread Safety地是逗enable地的状态，
那么你需要下载不带逗NTS地这个标志的。逗VC9地是用来标记编译器的，现在只有 VC9 的可以下载。
当然也可以根据 phpinfo() 里面的逗Compiler地属性去判断。
安装 Phalcon 时，不能以操作系统是多少位的来判断下载哪个安装包，而是要以 phpinfo() 里面逗Architecture地属性为准！
因为Phalcon 是作为PHP的扩展存在的，当然要以PHP是多少位的为准！
下载phalcon 把phalcon.dll 放到相关目录,一般是ext里面 在php.ini中添加 extension=phalcon.dll 重启环境print_r(preg_grep('/^phalcon/i', get_declared_classes()))
