entry level issue: || (OR) operator

When I use the || (OR) operator in my if statement below I end up in an endless loop.

For sake of simplicity here is the var_dump:

$auth "0" 
$id "2" 
$enabled "1" 
$page "auth-login.php"

If the criteria below is not met in the if statement then it will forward the user to auth-login.php (this is not applicable if the current $page is auth-login.php and auth-login-validate.php).

Statement without || (OR) operator: Forwards to auth-login.php as intended, but must also include auth-login-validate.php

if ($auth == '0' && $id != '1' && $enabled == '1' && $page != 'auth-login.php') {

header('Refresh: 0; URL=auth-login.php');
die();

}

Statement with || (OR) operator: Forwards to auth-login.php endlessly in a loop.

if ($auth == '0' && $id != '1' && $enabled == '1' && $page != 'auth-login.php' || $auth == '0' && $id != '1' && $enabled == '1' && $page != 'auth-login-validate.php') {

header('Refresh: 0; URL=auth-login.php');
die();

}

Will be some precedence related error. Make sure to put the parentheses where you intend to encapsulate the "OR" parts
