[PHP] Developing a recursive command parser

[Straps <fstraps@xxxxxxxxx>]

Hi all, i'm trying to develop an application able to interpret
commands loaded from a database or any other source similiar to this

$strParam = 'title=%SESSION(sessionvar)'
or a more complicated
$strParam = 'title=%SESSION(sessionvar_%COOKIE(mycookievar))'

What I need, is to find any special command starting width a
configurable special char (% in this case), get the text inside it and
elaborate it...

The final result could be a simple string like these
$strParam = 'title=My Session Title'
and
$strParam = 'title=My Session and Koookie Value'

I'm starting to working on it, do you know if is there a way to
accomplish to this using PCRE or if there is something just developed?

Thanks, Straps
