hi & thx for your replies....
@chris: thats exactly what I do right now, but I consider it a "workaround",
because I have to use session_register ("count"); first. the funny thing is,
that
when I call this page without an session id...
(just check.php instead of check.php?PHPSESSIONID=2178362178blah,
I disabled cookies for testing)
...PHP generates a session because of the session_register ("count");
command
even though I have "session.auto_start=0" in my php.ini...
If I press the refresh button of my browser I will have another session
generated
by PHP.......and another......and another.......and another....I think that
shouldn't
be. Anyway, its a very comfortable way to create loads of little (and
useless)
sessionfiles on my server ;)
@kaab & chadwick:
jepp, but session_register ("count"); also does the job. the problem is
that I don't want
PHP to generate a session if there is none on this page (check.php).....the
only way at the
moment seems to be that I:
1. session_register ("count"); (or sesstion_start();)
2. if (isset($count)) echo "everybody is happy";
else destroy_session(); // because there was an session generated
"accidentely")
humm. not very nice style. I expected the session_is_registered() function
to check for
the given vars in a session without the need of "session_start()" first. In
the end its not
too difficult to implement...
1. ist there a file called "sess_aSessionID" in session.save_path? [yes |
no]
2. [no] -> return false; (because there is no session)
3. [yes] -> open "sess_aSessionID" and check characters for aString [found |
notfound]
4. [notfound] -> return false;
5. [found] -> return true;
thats it (and what I expected).....and I wouldn't be forced to start a
session to find out.
I haven't been lazy and read some chapters about sessions.....but still the
"session_is_registered()"
function looks as useful to me as a "ceil(1);".
