Meta Refresh To Relative File

Question

Hi all,

I'm making a web app and I'm checking for the presence of a configuration file to determine whether or not to run the installation script. However, since it is a web app, I have no idea at what URL this script will be stored.

Is there any way to redirect a page, either using PHP or HTML, to a relative file?

Thanks in advance!

Answer 1

in PHP you can use header('Location: http://www.example.com/'); but it must be used with full url, not the relative one, so you just need to build full url from your relative url and use header

Answer 2

I found that I could just do this:

header('Location: ./install.php')

Answer 3

You can reconstruct the URL of the currently executing script using the 'SCRIPT_NAME' variable set by mod_php. From there it's just a matter of relative path manipulation to construct the absolute URL of the script you want to redirect to.

<?php
$scheme = $_SERVER['HTTPS'] ? 'https' : 'http';
$host = $_SERVER['HTTP_HOST'];
$basedir = dirname($_SERVER['SCRIPT_NAME']);
header("Location: {$scheme}://{$host}{$basedir}/redirect_target_page.php");
