修剪 [英] trim

问题描述

对某些人来说，这可能看起来很蹩脚，但是我已经把我的大脑想到了这个想法，因此把自己扔到了小组：


问题的基本分类


$ CurrentSite = $ _SERVER [" HTTP_HOST"];

<？php echo $ CurrentSite;？>


我只希望''domain.com''部分显示..即使主持人是
www.domain.com 或whatever.domain.com


我只是想显示domain.com，我是正确地认为定期的

表达式将是解决方案吗？


任何帮助都会节省我的理智。


谢谢

解决方案

CurrentSite =

_SERVER [" HTTP_HOST"];

<？php echo

CurrentSite;？>


我只想显示''domain.com''部分..即使主持人是 www.domain.com 或whatever.domain .com


我只是想显示domain.com，我是否认为定期

表达式是解决方案？

this may seem so lame to some, but I have exausted my brain trying to figure
this out, and therefore throw myself at the group:

basic breakdown of problem

$CurrentSite = $_SERVER["HTTP_HOST"];
<?php echo $CurrentSite ;?>

I only want the ''domain.com'' part to display.. even if the host is
www.domain.com or whatever.domain.com

I just want to display the domain.com, am I right in thinking that regular
expressions would be the solution?

any assistance would save my sanity.

Thanks
