当前域上的元刷新

Question

I'm trying to refresh page on the domain that it has been opened on, website can be accessed from multiple domains so I want to use the current one.

I tried

$url = "http://" . $_SERVER['HTTP_HOST']  . "/p.php" . "\">";
echo "<meta http-equiv=\"refresh\" content=\"0;url="; echo $url;

But that redirects me to: p.php without any domain, same result using $_SERVER['SERVER_NAME']

Not sure what I'm doing wrong ?

Answer 1

You don't need to use any $_SERVER value. Just:

<meta http-equiv="refresh" content="0; url=/p.php">

The browser will use the same domain as the one it's currently visiting when it constructs the complete URL to which to redirect itself.
