PHP获取完整的服务器名称，包括端口号和协议 [英] PHP getting full server name including port number and protocol

问题描述

在PHP中，是否存在可靠以及获取这些内容的好方法:

In PHP, is there a reliable and good way of getting these things:

协议:即http或https 伺服器名称:例如本地主机 端口号:例如8080

Protocol: i.e. http or https Servername: e.g. localhost Portnumber: e.g. 8080

我可以使用$_SERVER['SERVER_NAME']获取服务器名称.

I can get the server name using $_SERVER['SERVER_NAME'].

我可以获取协议，但是我认为它并不完美:

I can kind of get the protocol but I don't think it's perfect:

    if(strtolower(substr($_SERVER["SERVER_PROTOCOL"],0,5))=='https') {
        return "https";
    }
    else {
        return "http";
    }

我不知道如何获取端口号.我使用的端口号不是80.它们是8080和8888.

I don't know how to get the port number though. The port numbers I am using are not 80.. they are 8080 and 8888.

谢谢.
