推荐答案

refer(r)er 可以在 $_SERVER 全局变量中找到.请注意，发送refer(r)er 是完全可选的，用户代理可以简单地决定不发送refer(r)ing url.

The refer(r)er can be found in the $_SERVER global variable. Please note that sending the refer(r)er is completely optional and a user-agent can simply decide to not send the refer(r)ing url.

$_SERVER['HTTP_REFERER']
