Unserialize data from "session.vars"

[ElWhite]

First of all - many thanks for the good program.

I try make integration RounCube with portal. For this purpose it is necessary obtain data of user which are in table cell "session.vars".
Having obtained these data, at once has applied to received line function "unserialize", but as result of it has turned out nothing.
Realisation of reception of these data tried look in a program code, but practically has found nothing.
How disassemble data from "session.vars"? Certainly it is possible find simply them in line by means of regular expression, but it is not beautiful


p.s. Excuse for my bad English language
