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:

[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 mikeboston welcome to TSDN,

can we see the php code that u are using to set the sessions and the php code where u are trying to access them.

thank you

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:

<?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:

echo "<p>". session_id() ."</p>";
 

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