什么是首选的PHP扩展?安全方面有什么偏好?

4
如果您要在IIS上安装PHP,除了默认的PHP扩展之外,哪些PHP扩展是好的选择?通常有哪些首选的安全扩展/配置?
我认为必须安装Fast CGI、CURL和GD库。还有其他建议吗?
我正在为一个朋友安装,他让我安装他可能在应用程序中使用的任何扩展。他计划安装诸如内容管理系统等应用程序。

这取决于你是否会使用这些扩展。

如果你安装了不需要的扩展,那么就会减慢服务器的速度。

我们应该如何知道你的朋友需要什么?问他就好了。 - NullUserException
更简单地问问题:托管公司安装的扩展名有哪些?比如你从GoDaddy购买了Windows Server的共享托管,他们已经安装了什么?我没有访问服务器上的PHPINFO来查看,这就是为什么我在这里寻求帮助的原因。 - JoHa

@john 我也不知道GoDaddy安装了什么。去问他们的技术支持或销售团队比问我们容易得多。 - NullUserException
我认为在StackOverflow上可能有经验丰富的Web托管人员。无论如何,谢谢 =) - JoHa

这是一个主要且良好运作的共享Web主机的phpinfo()转储。几乎任何类型的CMS在其上都可以良好地运行,并具有良好的数据库和其他库支持。请查找其中的扩展:
