Exporting script output to csv

Hi, i have script for get all groups that a user is member of. Works correctly, but  i cant export it to csv file. output shows PS terminal just. any ideas what i exactly must  add to script?

 

Import-Module ActiveDirectory
Get-ADUser -SearchBase "OU=Users,DC=domain,DC=local" -Filter * | foreach-object {
write-host "User:" $_.Name -foreground green
    Get-ADPrincipalGroupMembership $_.SamAccountName | foreach-object {
        write-host "Member Of:" $_.name
    }
}
