http / php：header：location重定向未重定向到正确的域

Question

I am setting up a mirror of an existing website on a new host in preparation for switching hosts.

The mirror is running on a subdomain of my account on the new host. I also have the mysql database working. However, when the php code attempts a redirect using header:location, instead of redirecting to the page at the new host, it is sending the viewer to the old host. I can't for the life of me figure this out because I cannot find anywhere in the code that mentions the domain itself. Paths are just relative.

Old host domain. mysebsite.com

Typing in above loads index.php.

New mirror site domain. mywebsite.myaccountname.newhost.com

Typing in above takes you to the right directory and loads the page index.php .

The redirects are set up as follows:

header("Location: products.php");

Instead of going to mywebsite.myaccountname.host.com/products.php on the newhost, it goes to mywebsite.products.php on the old host.

Note I did name my subdomain on the new host mywebsite--the same as the domain of the current website, but I can't see how that would matter.

Thanks for any suggestions of what could be causing this.

Answer 1

try to use:

$server = $_SERVER['SERVER_NAME'];
header("Location: http://$server/products.php");
