推荐答案

可以在中找到refer（r）er $ _SERVER 全局变量。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推荐（r）网址。

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']
