passing arguments to subroutine

[c]

i am in need of a head check. mine hurts and i am afraid my code is the cause.
i am trying to pass an argument to a subroutine i have built that generates a .htaccess file. my question is whether or not i am calling the right variable as it is passed to my sub.

my @webhost = glob("$www/*");

if ($panel) {
  for my $i(@webhost) {
    if ( -d $i ) && ( $i ne "lost+found" ) && ( $i ne "DEFUNCT" ) {
      if ( -d $i/controlpanel ) {
        system("cp -fRp $dir $i");
      } else {
        mkdir $i/controlpanel/;
        system("cp -fRp $dir $i");
      }
    }
    htaccess($i);
  }
}

sub htaccess {
my $fqdn = shift;

open(FH,">/www/$fqdn/controlpanel/.htaccess");

print<<HTA;
AuthUserFile /etc/htsec/$fqdn.ht
AuthName "Hosting Administration"
AuthType Basic
require valid-user
HTA

close(FH);
}

my biggest concern is that the $fqdn is being set to the $i value without any gotchas, e.g. do i need to chomp this bad boy to create the file or any other ghosts i may not be seeing. also, i am using shift to pull the value out of @_ in my subroutine. is this the right way to do this? granted in this example $i is a single value rather than multiple strings being passed to the sub-routine, but i am sure i am going to make use of this again in the near future.
