hi

i recently wrote an nginx module that can extract certain values out  
of a serialized php session. in my case i’m retrieving the php session  
from a memcache. this thing isn’t tested in prod, in fact i started it  
yesterday. but it seems to work and i can’t find any bigger problems  
with it at the moment.

currently it works like this:

33 location / {  
34 eval $session {  
35 set $memcached\_key  
“d41d8cd98f00b204e9800998ecf8427e:5b9hm9rspbgajg22eqpqs6ang1”;  
37 memcached\_pass 192.168.1.237:11210;  
38 }  
…  
44 php\_session\_parse $admin\_right $session  
“symfony/user/sfUser/attributes|s:10:"subscriber";s:7:"isAdmin"”;  
…  
53 if ($admin\_right = “b:1”)  
54 {  
55 # do something  
56 }

i think the format how i am specifying the value that i want to  
extract from the session might be a little confusing (and there are no  
docs yet). in the example the value that i want to extract is  
specified with the string:

"symfony/user/sfUser/attributes|s:10:"subscriber";s:7:"isAdmin"

which means on the toplevel array i want the element  
“symfony/user/sfUser/attributes”, second level i want the element  
“s:10:"subscriber"”, third level i want the element  
“s:7:"isAdmin"”. separators between the elements are ; and |. this  
might seem confusing, but thats the way how its done in the php  
session serialization…

i would be happy about some feedbacks. could a thing like this be  
useful? i’m sure there are still bugs too…
