Session Variables in Red Hat?

mikeboston

Hi,

I am attempting to use php session variables on a server which is running Red Hat Linux, but the variables don't seem to be getting passed between pages. I have tried the same exact test script on my third party webhost, and it works just fine. Does anyone know of anything that needs to be changed in a default Red Hat php setup?

This is the test script that I am using:
http://php.about.com/od/advancedphp/ss/php_sessions.htm

This is what I was given as the default setup for redhat:

Expand|Select|Wrap|Line Numbers

 
[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.

session.save_path = /var/lib/php/session
 
; Whether to use cookies.

session.use_cookies = 1
 
; 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 =
 
; 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     = 1000
 
; After this number of seconds, stored data will be seen as 'garbage' and

; cleaned up by the garbage collection process.

session.gc_maxlifetime = 1440
 
; 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 = 0

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
 
; trans sid support is disabled by default.

; Use of trans sid may risk your users security.

; Use this option with caution.

; - User may send URL contains active session ID

;   to other person via. email/irc/etc.

; - URL that contains active session ID may be stored

;   in publically accessible computer.

; - User may access your site with the same session ID

;   always using URL stored in browser's history or bookmarks.

session.use_trans_sid = 0
 
; The URL rewriter will look for URLs in a defined set of HTML tags.

; form/fieldset are special; if you include them here, the rewriter will

; add a hidden <input> field with the info which is otherwise appended

; to URLs.  If you want XHTML conformity, remove the form entry.

; Note that all valid entries require a "=", even if no value follows.

url_rewriter.tags = "a=href,area=href,frame=src,input=src,form=fakeentry"

Thanks for any help that you can provide.

Hi Epots, yes, the code is the exact code that you find at that link above. The link goes to a php session variables tutorial. Here is the script in action, working just fine: http://gurry.com/session

Thanks,
Mike

page 1:

Expand|Select|Wrap|Line Numbers

 
<?php 

session_start(); 
 
// makes an array 

$colors=array('red', 'yellow', 'blue'); 

// adds it to our session 

$_SESSION['color']=$colors; 

$_SESSION['size']='small'; 

$_SESSION['shape']='round'; 

print "Done";

?>
 
page 2:

<?php 

session_start(); 

Print_r ($_SESSION);

echo "<p>";
 
//echo a single entry from the array

echo $_SESSION['color'][2];

?>

This is most likely a problem with your PHP configuration.

Try adding this to the top of your page, after the session_start() function call:

Expand|Select|Wrap|Line Numbers

echo "<p>". session_id() ."</p>";

This will print the session id, which should stay the same throughout the session.
