$_SERVER['HTTP_HOST'] 得到的host是带端口号的,理论上讲host为主机名,不应该带端口号。


回复讨论(解决方案)

$_SERVER['HTTP_HOST'] 不会带有端口号
$_SERVER['SERVER_PORT'] 才是端口号

$_SERVER['HTTP_HOST'] 不会带有端口号
$_SERVER['SERVER_PORT'] 才是端口号
亲测,非80端口时,$_SERVER['HTTP_HOST']是带有端口号的。

那你好好研究下php的全局变量$_server吧。

$_SERVER['HTTP_HOST'] 会带有,因为是http中request头部信息的Host头域 。

Host头域 

Host头域指定请求资源的Intenet主机和端口号,必须表示请求url的原始服务器或网关的位置。HTTP/1.1请求必须包含主机头域,否则系统会以400状态码返回。
