安装PHP5.25后出现网页空白，无内容

今天把php有原来的5.12升级到了5.25，结果打开网站出现空白，运行phpinfo显示如下：

与php5.12比较，Registered Stream Socket Transports 项少了ssl, sslv3, sslv2, tls ，不知这几项什么作用？
运行php5.12参数图

请师傅们教教我

服务器软件	Apache/2.0.63 (Win32) mod_ssl/2.0.63 OpenSSL/0.9.7m PHP/5.2.5
服务器 MySQL 版本	5.0.27-community-nt

闲的升级，稳定后就不用升级了，这是服务器大哥！

无法开启内存优化，感到少点什么

可以尝试更新或清空下站点缓存

装傻瓜版最简单。

今天装了IIS 7.5 +php 5.33 结果出现
错误摘要
HTTP 错误 500.0 - Internal Server Error
无法显示页面，因为发生内部服务器错误。

详细错误信息
模块 FastCgiModule
通知 ExecuteRequestHandler
处理程序 PHP via FastCGI
错误代码 0x00000000
哎。郁闷死了！

我顶了，2008下，各个版本搞了几天，没搞好。

不明白 帮顶
