php从网址中删除www [英] php removing www from url

问题描述

当URL没有https或URL中有www时，我在FB应用程序上遇到错误.我只是要去掉www的网址.

I am getting an error on a FB app when the url does not have the https or and has a www in the url. I am just going to strip the url of the www.

如果下面的代码不在网址中，则下面的代码添加https，但我也将如何删除www ?

The code below adds the https if it is not in the url but how would I remove the www as well?

if(!isset($_SERVER['HTTPS']) || $_SERVER['HTTPS'] == ""){
    $redirect = "https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];
    header("HTTP/1.1 301 Moved Permanently");
    header("Location: $redirect");
}

推荐答案

if(!isset($_SERVER['HTTPS']) || $_SERVER['HTTPS'] == ""){
    $redirect = str_replace('www.', '', "https://".$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI']);
    header("HTTP/1.1 301 Moved Permanently");
    header("Location: $redirect");
}

最简单的方法.
