How to read Session file

[Anon]

Below is the contents of a session file. If I were to break this down, how would I read it...?

valid_user|s:8:"n0000749";weekmenu|b:0;time|b:0;

I know that "valid_user" is the registered var, and "n0000749"; is the user name.
what is the "s:8".

"weekmenu" is another registered var(array)...what does "|b:0;" tell me...?

"time" is another array.

I do not see any results, for the arrays when I use
print_r($weekmenu);

I have read many, many posts on sessions, but I have not seen any that describe the content in deatil...??!

thanx

I believe the s is for string and the 8 is the string length.

I kinda thought that...

If this is true then the two arrays
"weekmenu" and "time" have show this in the file...
"weekmenu|b:0;time|b:0;"

Not sure what the "b" means...but the "0" could mean empty...?!!

Uhm... why don't you just use PHP to read it?
