Getting a list of users and permission from a folder

Question

I run this command to get a a list of users and permission from a folder
$project_folder = "\\servername\foldername"
get-acl $project_folder | %{ $_.Access  } | ft -property IdentityReference, AccessControlType, FileSystemRights > folder.csv.
This only lists information for 1 folder.
If i have multiple folders how should the code be modified?

Answer 1

this is the code i am looking for 
 $project_folder
= "\\servername\foldername\foldername1"
get-acl $project_folder | %{ $_.Access  } | ft -property IdentityReference, AccessControlType,
FileSystemRights > folder.csv.
I  run this code and this gives me the information for only the folder 'foldername1'.
Ex. i need a list of users who have permmission in \\servername\foldername\foldername2.
i run the code and it gives me the permissions and list of users in foldername2.
This is the issue
IF there are multiple folders \\servername\foldername\foldername2, \\servername\foldername\foldername1,
i need to run the code each time for 1 folder. 
is there a command where i can combine the path of these 2 or more folders and export
it to csv
Ex.  $project_folder
= "\\servername\foldername\foldername1",
"\\servername\foldername\foldername2"
get-acl $project_folder | %{ $_.Access  } | ft -property IdentityReference, AccessControlType,
FileSystemRights > folder.csv.
This will give me the list of users and the type of access they have in foldername1 and
foldername2
