Problem session_unregister

[Artur]

whem i use the function session_unregister to clean a variable from my session, if in the same session i do a session register to the sam variable, the variable contains the the last value, and i don't want that, and it should not happen.

example :

session_register("a&quot
$a = 1
session_unregister("a&quot

.....



session_register("a&quot

-- and know the variable contains "1" and it should be empty

Try using [tt]session_destroy()[/tt]. That destroy's all session data.

Hope this helps,

I don´t want to destroy the session, because i have other variables that i don't want to lose. I can build a function that it destroy the session, and immediatly it start a new session width all the variables that i want.

Other solution is to reset the variables .

But i think that it should be another way

try unset($your_var) whihc will destry that var in the session data

I would try using the unset() function prior to using the session_unregister.

remember that even though you have called session_unregister("a&quot, your variable still exists ($a = 1).

Also, as good practice, you should set your variable then call session_register.

$a = 1;
session_register("a"

then you can call do

unset($a);
session_unregister("a"

also keep in mind that the unset($a) is only required if you set a variable, register a session var and then want to kill the variable all within the same instance of script execution. If you set the variable and register it, you wont need to use unset($a) because the scalar variable of $a no longer exists in its hard form (only exists in the session).

I hope I did not confuse you here. Sorry if I did.
