[PHP] [Q] session variables wouldn't keep contents.
Hi guys,
Some php programs doesn't seem to work normally in a certain
server. Those wokred correctly in my Debian box.
Session is the problem.
It seems that the contents of session variables disappears after
reloading the php page. Here is the program.
test.php
";
session_register("name");
$HTTP_SESSION_VARS["name"] = "test";
echo "newly registered";
}
$session_name = $HTTP_SESSION_VARS["name"];
echo session_encode()."";
echo "session_name = $session_name";
?>
test.php
Can I handle it with only php configuration file? Or Do I have to
modify my php programs?
In addition to this, I have a few questions about the work of session
in php 4.0.4
Q1) Do I have to use session_start() explicitly although session.auto_start
is set to 1 in php.ini?
Q2) Do I have to use session_register("variable_name")?
In my Debian woody box, it seems to run well without it.
Regards,

I modified that way. But no effect. still not work correctly.
After reloading, session variables are emptied. ;(

YO> I'm not sure what do you want to handle "it".
Just *poor* english. ;P
solving the above trouble.
YO> Starting session can handle in php.ini and inside code.

YO> No.
YO> Session will be started automatically, so programmer does not have to write it.
YO> I recommend to write session_start(), though.
YO> Also, session will be started implicitly if programmer uses session functions

it,

YO> It seems works fine on my box without it when I use $HTTP_SESSION_VARS at
least.
YO> I think it will not work without $HTTP_SESSION_VARS.
YO> (PHP4.0.4pl1/Apache/RedHat Linux7)
I use only $HTTP_SESSION_VARS. ;)

Re: [PHP] [Q] session variables wouldn't keep contents.
My second example program. a.php a.php result is as following. !name| and, /tmp/sess_7d755f490ba4e50da20d7167e2966771 file has only "!name|" without any stuff relating to "test" which I inserted into $HTTP_SESSION_VARS["name"] I can't figure out why this odd things happen. apache and php's configuration files are the same as thoes in my home computer and both of two computer use Debian/woody. Anybody has some clues about it? why session variables' contents wouldn't stored.

(You may see some errors like YO> oops header already sent) Certainly are there data files which look like "sess_sessionid" in /tmp and changed everytime when I reload the web page. And sessoinid is the same as the value of cookie variable, PHPSESSID. Up to this stage does things seem to go well. I think so. phpinfo result looks correct...almost. *THERE'S NO HTTP_SESSION_VARS* in PHP variables!! although I used session_start() and session_register()! It is incorrect, isn't it? I can see session module info in my phpinfo and it is correct. ;( Surely I set error_reporting = E_ALL display_errors = On display_startup_errors = On and no error/warning messages in the page. YO> Something must be wrong, since your environment is similar to that I have. I found something! If I set register_globals to Off in php.ini, then session *seems* to work well. In /tmp, session data file contains both of variable name and value and I can use $HTTP_SESSION_VARS["variable"]. BUT, as before is there no HTTP_SESSION_VARS in PHP variables section of phpinfo. I'm so confused and think things are getting weirder. ;( YO> Regards, YO> Yasuo Ohgaki YO> -- YO> PHP General Mailing List (http://www.php.net/) YO> To unsubscribe, e-mail: [EMAIL PROTECTED] YO> For additional commands, e-mail: [EMAIL PROTECTED] YO> To contact the list administrators, e-mail: [EMAIL PROTECTED] -- Chung Ha-Nyung <[EMAIL PROTECTED]> -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

[PHP] [Q] double quote(") is auto-transformed into (\")!
I found that when I pass the double quote(") through get(or post) method,
it is transformed into slash + double quote (\").
Although it seems useful in making SQL query, it's really annoying whenever
I pass the value to the other php page through get/post again.
Can I turn off this feature?
