Using PHP in a header to redirect a webpage

Question

I am using php to redirect a php file:

 header("location:viewprofile.php?id=<?php echo $id; ?>");

The problem is the php is not taken as php and is taken literally, how can I echo the variable in this header?

Answer 1

header("location:viewprofile.php?id=$id");

Answer 2

try this :

header("Location: viewprofile.php?id={$id}");

1) notice the capital "L" in Location, although http headers should be case-insensitive (as by the specifications), some browsers treat them as case-sensitive (IE).

2) you should not use relative paths if possible, because if a trailing slash is left by the browser in the url, you might be redirected to the wrong page (ie http://domain.com/folder/ will redirect to http://domain.com/folder/viewprofile.php?id=5 )

Answer 3

No need to echo it. just use the following code:

header("location:viewprofile.php?id=".$id);

the stored value in the variable $id will be attached to the header string.
