问题描述

如何检测iPhone是否有视网膜显示器？有可靠的方法吗？无论是纯PHP还是Zend Framework最好的方式。

How can I detect if an iPhone has a retina display or not? Is there a reliable way? Either pure PHP or preferably Zend Framework way of doing this.

推荐答案

你必须考虑到你想要获得客户端这一事实服务器端的信息。

You must consider the fact that you are trying to get client side information on the server side.

您似乎无法使用纯PHP或Zend框架检测到显示。

It would seem that you are unable to detect the display with pure PHP or Zend framework.

此外，您可能从PHP访问的客户端的UserAgent信息基于操作系统，而不是硬件，因此无法帮助您。

It furthermore seems like the UserAgent information from the client, that you might access from PHP is based upon the OS, not the hardware, and thusly does not help you.
