如何处理不同环境的php重定向

Question

I'm developing a php application that involves creating a session and redirecting a user to a dashboard page after the session is successfully created. I currently use the following code:

if ($success) {
    header("Location: http://www.mydomain.com/dashboard.php");
}

I'm working on making my application available for others to download and use on their own servers, so I'm looking for another way to write the redirect code above so that it's not restricted to only mydomain.com . How do you handle php redirects for any domain? Can header() work with relative paths such as header("Location: ./dashboard.php"); ?

Answer 1

The best way for do this is to keep a configuration.php file where you can store all this information (customized on final user needs) and retrieve all you need from this file.

This file could be "composed" with an init script or something like this (if you have a backoffice, even directly stored in DB or make writeable this file by your backoffice itself, with all risks of the case )

Answer 2

In the past I have used the $_SERVER global to get the domain of the current website.

echo $_SERVER['SERVER_NAME'];

One downside to this approach is that the application may not be running in the top directory. So, normally what I have done is in the index.php (all requests are routed through index.php) I defined a constant with the base path and the domain, so something like this:

define('BASE_PATH', 'http://' . $_SERVER['HTTP_HOST'] . pathinfo($_SERVER['PHP_SELF'])['dirname']);
