I have recently installed PHP on my home computer so I don't have to ftp everytime I want to test code.  Everything works great except I can't access session variables outside the page they were created in.  I have followed several tutorials online unsuccessfully.  I have included the session portion of my PHP.ini file.  I would really appreciate it if someone could take a look at it and tell me what I'm doing wrong.  By the way, I did manually create a folder at C:\PHP\sessions, the session location in the ini file.  Thanks!
[Session]
; Handler used to store/retrieve data.
session.save_handler = files
 
; Argument passed to save_handler.  In the case of files, this is the path
; where data files are stored. Note: Windows users have to change this
; variable in order to use PHP's session functions.
;
; As of PHP 4.0.1, you can define the path as:
;
;     session.save_path = "N;/path"
;
; where N is an integer.  Instead of storing all the session files in
; /path, what this will do is use subdirectories N-levels deep, and
; store the session data in those directories.  This is useful if you
; or your OS have problems with lots of files in one directory, and is
; a more efficient layout for servers that handle lots of sessions.
;
; NOTE 1: PHP will not create this directory structure automatically.
;         You can use the script in the ext/session dir for that purpose.
; NOTE 2: See the section on garbage collection below if you choose to
;         use subdirectories for session storage
;
; The file storage module creates files using mode 600 by default.
; You can change that by using
;
;     session.save_path = "N;MODE;/path"
;
; where MODE is the octal representation of the mode. Note that this
; does not overwrite the process's umask.
;session.save_path = "/tmp"
"session.save_path=C:\PHP\sessions"
 
; Whether to use cookies.
session.use_cookies = 1
 
;session.cookie_secure = 
 
; This option enables administrators to make their users invulnerable to
; attacks which involve passing session ids in URLs; defaults to 0.
; session.use_only_cookies = 1
 
; Name of the session (used as cookie name).
session.name = PHPSESSID
 
; Initialize session on request startup.
session.auto_start = 0
 
; Lifetime in seconds of cookie or, if 0, until browser is restarted.
session.cookie_lifetime = 0
 
; The path for which the cookie is valid.
session.cookie_path = /
 
; The domain for which the cookie is valid.
session.cookie_domain =
 
; Whether or not to add the httpOnly flag to the cookie, which makes it inaccessible to browser scripting languages such as JavaScript.
session.cookie_httponly = 
 
; Handler used to serialize data.  php is the standard serializer of PHP.
session.serialize_handler = php
 
; Define the probability that the 'garbage collection' process is started
; on every session initialization.
; The probability is calculated by using gc_probability/gc_divisor,
; e.g. 1/100 means there is a 1% chance that the GC process starts
; on each request.
 
session.gc_probability = 1
session.gc_divisor     = 100
 
; After this number of seconds, stored data will be seen as 'garbage' and
; cleaned up by the garbage collection process.
session.gc_maxlifetime = 1440
 
; NOTE: If you are using the subdirectory option for storing session files
;       (see session.save_path above), then garbage collection does *not*
;       happen automatically.  You will need to do your own garbage
;       collection through a shell script, cron entry, or some other method.
;       For example, the following script would is the equivalent of
;       setting session.gc_maxlifetime to 1440 (1440 seconds = 24 minutes):
;          cd /path/to/sessions; find -cmin +24 | xargs rm
 
; PHP 4.2 and less have an undocumented feature/bug that allows you to
; to initialize a session variable in the global scope, albeit register_globals
; is disabled.  PHP 4.3 and later will warn you, if this feature is used.
; You can disable the feature and the warning separately. At this time,
; the warning is only displayed, if bug_compat_42 is enabled.
 
session.bug_compat_42 = 1
session.bug_compat_warn = 1
 
; Check HTTP Referer to invalidate externally stored URLs containing ids.
; HTTP_REFERER has to contain this substring for the session to be
; considered as valid.
session.referer_check =
 
; How many bytes to read from the file.
session.entropy_length = 0
 
; Specified here to create the session id.
session.entropy_file =
 
;session.entropy_length = 16
 
;session.entropy_file = /dev/urandom
 
; Set to {nocache,private,public,} to determine HTTP caching aspects
; or leave this empty to avoid sending anti-caching headers.
session.cache_limiter = nocache
 
; Document expires after n minutes.
session.cache_expire = 180

The property settings do not start with a quotation mark. This:
"session.save_path=C:\PHP\sessions"

should be:
session.save_path="C:\PHP\sessions"

Ah yes, you are right, but that still didn't do the trick.  In case I'm missing something obvious I included the files below that I'm using to test it.  Thanks!


<? // file test.php
session_start();
session_register('PASS');
$PASS="It works";
header("Location: sessionTEST.php");
?>
 
<? //File sessionTEST.php
session_start();
echo $PASS;
?>

You retrieve it as follows:
<? //File sessionTEST.php
session_start();
echo $_SESSION['PASS'];
?>

BTW: The common way to set the session on the most recent version of php is as follows:
<? // file test1.php
session_start();
$_SESSION['PASS'] = "It works";
header("Location: sessionTEST.php");
?>

The way you have is also correct, but is the old way. Its not wrong. Just letting you know because you are most likely to find the syntax above on sample codes when posting here :)

That actually fixed the problem.  Strange, I've been doing it the other way for years.  So I guess you don't have to register the session variables at the top of each page anymore?  Thanks!!!
