PHP:从字符串内的URL中删除"WWW" [英] PHP: Remove 'WWW' from URL inside a String

问题描述

当前，我正在使用parse_url，但是数组的主机项还包含了我不想要的'WWW'部分.我将如何删除它?

Currently I am using parse_url, however the host item of the array also includes the 'WWW' part which I do not want. How would I go about removing this?

$parse = parse_url($url);
print_r($parse);
$url = $parse['host'] . $parse['path'];
echo $url;

推荐答案

$url = preg_replace('#^www\.(.+\.)#i', '$1', $parse['host']) . $parse['path'];

这不会删除www.com中的www，但是www.www.com会导致www.com.

This won't remove the www in www.com, but www.www.com results in www.com.
