Problem solved: the reason print($url) caused the program to work is because
the page calling Secure_Login no longer existed and therefore the print
forced a die--I assume. I included a die in the redirect function and all
was well. Including die in the redirect function made sure the page that
was redirected stop executing. The final question to the PHP community with
this issue is: if a page myphppage.php has a redirect in it, how can it
execute code after the redirect if it no longer exists? Is it because the
server side code cares not that it has been redirected and only what is
happing inside the php code?

Subject: Function Misbehaving
The following function is a basic user auth prep procedure for multiple
pages. If the url desired is different than the default a url is supplied.
This function works most of the time flawlessly; except, on some pages when
the url has a value that was passed, the function still thinks url is NULL
until it is used, such as printing it or assigning another variable its
contents. Another way to eliminate this sporadic problem is to rename the
parameter url to something else, such as url2. There are no global or
session vars with the url name. Why does php think url is null when it is
not, but only fault in this manner part of the time. Any help would be
appreciated.
// Code
function Secure_Login($user,$pass,$db,$pg,$url=NULL)
{
//print($url); if I uncomment this url
is no longer null or if I rename url to url2
$checkuser =
is_user($user,$pass,$db);
if (!$checkuser)
{
Secure_Email($pg);
if(isset($url))
{
Go_Page($url);
}
else
{
Go_Page("./login.php?login_error=2");
}
}
}

Do you have exit after the redirect?
Try:
<?php
header("Location: http://www.example.com/";); /* Redirect browser */
/* Make sure that code below does not get executed when we redirect. */
exit;
?>
See http://uk.php.net/header for more info.
