Variable Page Redirect

[SyntheticShield]

Im not sure that it is possible, but I thought I would post and ask anyway.

 

I want to use a page redirect such as:

 

<?php
header("Location: http://www.redirect-to-home.com/");
exit;
?>

 

However, due to the nature of the redirect and the header having to be sent first, Im not sure how I could use a variable or probably better, something like HTTP_HOST.

 

In a post I made elsewhere on here, someone posted this code:

 

if($_SERVER['HTTP_HOST'] == "localhost"){
// For local development
    define('SITEURL', 'http://' . $_SERVER['HTTP_HOST'] . '/template');
    define('SITEPATH', $_SERVER['DOCUMENT_ROOT'] . 'template');
}
else{
// For production web
    define('SITEURL', "http://" . $_SERVER['HTTP_HOST']);
    define('SITEPATH', $_SERVER['DOCUMENT_ROOT']);

 

I began thinking then, I wonder is something like that could be used as a page redirect as a very basic and simple prevention to direct access to a specific folder on the site?  But Im not sure how to make it work, Im just not that experienced in PHP yet.

 

I dont know if using an index.html file would be better over an index.php file either.  Im still experimenting a little trying to figure things out.

 

So is there a way to use a php variable to redirect someone back to the home page?  I know you can use .htaccess and things like that as well, but I wanted to see if this could be done also.  Thanks in advance for any help.

Uggggh, nevermind, I got it.  I was all off base, LOL

 

if($_SERVER['HTTP_HOST'] == "localhost"){
// For local development
    define('SITEURL', 'http://' . $_SERVER['HTTP_HOST'] . '/template');
    define('SITEPATH', $_SERVER['DOCUMENT_ROOT'] . 'template');
}
else{
// For production web
    define('SITEURL', "http://" . $_SERVER['HTTP_HOST']);
    define('SITEPATH', $_SERVER['DOCUMENT_ROOT']);
}

$URL= SITEURL;

header ("Location: $URL");
