[Resolved] session_decode

[bfuzze_98]

I'm having some trouble figuring out how to get my session data back into readale/usable form after encoding and writing it to a text file. This comes straight from the manual:

$sfile = "messages/message.txt"; 
$h=fopen($sfile,'r');
session_decode($h,filesize($h));
fclose($h);

but when I echo or try to print_r the session variable,
ie.

print_r($_SESSION['fname']);

I get no response.
What am I doing wrong?

"session_decode()" takes one argument, a string. You're passing it a file handle and an integer.

session_start();
$sfile = "messages/message.txt";  

$str = file_get_contents($sfile);
session_decode($str);

Edit: What manual are you referring to?

Correction, the code posted earlies came from the comments section of the php manual under session_decode.

I'll give this a try, thanks for the response!

You'll want to keep in mind that the encoded data isn't written until the script ends, "session_write_close()" is called, or you write the sting to file. So if you assign a value to a session element, call "session_encode()", then change the value later in the same script, the second value will be the one encoded if the encoded data hasn't been written. Also, "session_decode()" will overwrite any elements of the same name that were changed. These will demonstrate:

test.php

session_start();
$_SESSION['test_1'] = 'original_1';
$_SESSION['test_2'] = 'original_2';
$_SESSION['test_1'] = 'new_1';
$sess_encode = session_encode();
$_SESSION['test_2'] = 'new_2';
$fp = fopen('sess_1.txt', 'wb');
fwrite($fp, $sess_encode);
fclose($fp);
session_write_close();
session_start();
$sess_encode = session_encode();
$fp = fopen('sess_2.txt', 'wb');
fwrite($fp, $sess_encode);
fclose($fp);
echo '<a href="test_2.php">click</a>';

test_2.php

session_start();
echo '<pre>';
print_r($_SESSION);
$sess = file_get_contents('sess_1.txt');
session_decode($sess) . '<br />';
print_r($_SESSION) . '<br />';
$sess = file_get_contents('sess_2.txt');
session_decode($sess) . '<br />';
print_r($_SESSION) . '<br />';
echo '</pre>';

Edit: I don't think I made it real clear, but my point is in there somewhere.
(BTW, I still haven't found the code you used. 🙂 )

Thank you for the info and sorry for the delay in response.

You are (were) using two different directories: "message" and "messages". If they (the directories) don't exist, the files won't be written. You should turn "error_reporting" on.

I just noticed that as well, sorry...
