Use a hash instead of five scalars. Then you can do:

my @found;
foreach my $field_name (qw/name vorname plz tel tel49/) {
  push(@found, $field_name) if ($my_hash{$field_name});
}

(Untested)

That will give you an array of all the fields that are set. This may or may not be helpful - you didn't say what you planned to do with the results.

Or more succinctly:

my @found = grep exists $my_hash{ $_ }, qw( name vorname plz tel tel49
+ );

Update: Good point below. Omit the exists if that's the desired behavior. MENTAL NOTE: NO POSTING OR UPDATING NODES BEFORE CAFFEINE TAKES EFFECT.

The original code doesn't consider an empty string to be "found", but exists will.
