i hate these sort of problems. weird unexplainable ones. on my not found page i have this right at the start:

Code:
<?php

/* if a corrected url submission redirect to it */

include ('/home/users/theusername/html/thewebsiteaddress.com/includes/contact.inc.php'); /* for mystriptslashes() and email address */

$host = $_SERVER['HTTP_HOST'].'/';

if( isset( $_POST['uri-submit']) ) {
	$corrected_uri = str_replace(' ','%20',trim(mystripslashes($_POST['corrected-uri'])));
	header( "Location: http://$host$corrected_uri" );
	exit;
}

/* bits for later */

$request_uri =  substr( mystripslashes($_SERVER['REQUEST_URI']), 1 );

?><!DOCTYPE html PUBLIC "-//W3C//DTD ....
note: putting
echo '<h1>', $host, '</h1>';
in after where $host is set prints out:
www.domainname.com/
the important thing for this question is the slash.

then later on in the not found page's code i have:
Code:
<h2><span class="url"><?php echo $host; ?><span class="wrong"><?php echo $request_uri; ?></span></span> not found</h2>
this prints out as
www.domainname.comxyz
where xyz is the not found page's part -- no slash. same $host variable ?!? wtf worked on a different server ok as well.

any ideas why the slash isn't on the $host variable a little later on, on the same page?

ok, just before posting this i though "i'd better check just in case $host isn't some previously used variable or something" and changed all (four) occurances of $host to $hostxyz and it's now printing out the slash ?!? any ideas what's going on there?

thanks.
