session encode/decode

[tuf-web_co_uk]

hey

i was wondering why does session_decode return a value of 1 if i do this

(note : a previous page did this - $_SESSION["greet"] = "hello"; )

<? 

session_start();
$strSess = session_encode();
echo $strSess;
echo "<br>";
$strses = session_decode($strSess);
echo $strses; 

?>

session_encode returns = greet|s:5:"hello";

how can i get the data back to the previous state which is "hello"

thanks

Comms

bool session_decode ( string data)

Probably because it returns true when successful, and false when it fails for some reason.

If you want "hello" note that

session_decode() decodes the session data in data, setting variables stored in the session.

Which I guess in your case would be $_SESSION['greet'] or maybe $greet.

does session_encode actually encode the session data?

from my experience it doesnt!

<?
session_start(); 
$strSess = session_encode(); 
echo $strSess; 
echo "<br>";
echo $_SESSION["greet"]; // returns 'hello', which isnt encoded
?>

why does this happen?

What version of PHP are you using? I found this:

for PHP4.2.2 user
if u use $_SESSION['abc'] = 1; without session_register
session_encode will ONLY works correctly in session write handler
e.g.: u may need to do session_encode() in shutdown functions
upgrade to PHP4.3.x would helps

Not having PHP4.2.2 around anywhere, I can't check. But 4.3.x works.

i 'tested' that script on php5 b2

if i didnt mention it

echo $strSess; // returns greet|s:5:"hello";

however like i did mention

echo $_SESSION["greet"]; // returns 'hello', which isnt encoded

both underneath session_encode();

😕
