php gets current page address

Suddenly can’t find what you want to use?

$_SERVER['HTTP_HOST']//获取域名或主机地址 

$_SERVER['PHP_SELF']//获取网页地址

$_SERVER["QUERY_STRING"]//获取网址参数 

If you want to output, add 'http://' in front of it

.$_SERVER['HTTP_HOST'].$_SERVER['REQUEST_URI'];//获取完整的url

$url='http://'.$_SERVER['SERVER_NAME'].$_SERVER["REQUEST_URI"]; 
echo dirname($url);//只取路径

Summary: In fact, I usually only use the URL parameters to make a judgment. Others are irrelevant. I hope it can help you. Bar.
