I prefer to pass as a reference.
# your code was passing an array ref, not a hash, but since you are asking
about
# hashes, i will switch to a hash
my $htmloutput = generate_navIndex( $outputDir, $pageName, \%arrayIndexPages
);
# this should work, but i have not tested.
sub generate_navIndex{
# the 3rd arg accepts the ref to the hash
my ( $paramPath, $paramPageName, $paramArrayIndexPages ) = @_;
my $output = "";
# deref like you would any has reference
while ( my ($key, $value) = each( %{$paramArrayIndexPages} ) ) {
$output .= "$key<br>";
}
return $output;
}
