Seit ich von WAMP (WinXP,Apache,MySQL,PHP) auf LAMP mit SuSe9.1 umgestiegen bin, funktionieren keine Session-Befehle mehr.

Sobald ich session_start() oder session_register() benutz, gib er mir nen fatal error: Call to undefined Function aus.

Was muss ich in welcher php.ini einfugen/ändern, damit es geht ?

Der Session-Teil bisher schaut so aus:
[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
session.save_path = /var/tmp

; 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 = /var/tmp

; The domain for which the cookie is valid.
session.cookie_domain = pcw.homeip.net

; 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 seperately. 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

; 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=,fieldset="
 
Dein PHP ist offenbar ohne Session-Modul kompiliert, d.h. du musst PHP neu kompilieren. Ich habe jetzt nicht mehr Zeit, aber in die Richtung solltest du weiter forschen (u.a. PHP Manual).

Edit: Sehe gerade, dass PHP per Default mit Session-Funktionen kompiliert wird, d.h. dein PHP wurde offenbar explizit mit "--disable-session" erstellt.
 
Fazit: Webserver manuell einrichten, und auf seltsame WAMP / LAMP Pakete verzichten...
Wieder was gelernt ;)
 
^^thx, ich werds im laufe des abends ma versuchen :)

Meld mich wieder bei Erfolg/Misserfolg
 
Klingt vielleicht blöd, aber gibts irgendwas tolles was so ne Session-ID kann ?

Ich bastel hier gerade was und schreib beim Login einfach die Microtime in ein Cookie und die DB (+IP+Login).

Ich seh da jetzt nicht den großen Unterschied außer, dass ich auch mit nem PHP ohne Session-Funktionen leben kann.
 
Den cookie kann der user natürlich ändern, was er bei einer session nicht kann, da liegt der cookie auf dem server wenn du es so sehen willst, ausserdem braucht der client keine cookies zu akzeptieren. ansonsten ist beides in etwa identisch.
