通过php中的变量重定向

Question

I have my link in a variable:
$actual_link = "http://$_SERVER[HTTP_HOST]$_SERVER[REQUEST_URI]";

I am passing the $actual_link through sessions to another page and want there to redirect it to main page i.e $actual_link for a particular condition.

The location("header:yoururl.com") doesn't work as it requires a definite url. So anything that can serve my cause?

Answer 1

You need to wrap array element in {} if you put it into a string

$actual_link = "http://${_SERVER['HTTP_HOST']}${_SERVER['REQUEST_URI']}";

and a key need to be a string in single quote.

or you can put array element outside of string

$actual_link = "http://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

olso if you want it to work with SSL use this check

$_SERVER['HTTPS'] == "on"

and put s after http

$protocole = "http" . ($_SERVER['HTTPS'] == "on" ? 's' : '');
$actual_link =  $protocole . "://" . $_SERVER['HTTP_HOST'] . $_SERVER['REQUEST_URI'];

then you can redirect the url using header

header('Location: ' . $actual_link);
