When you return from a sub, you exit the sub at that point, so the rest of it doesn't get executed.

You want this: 

sub get_html {
  my @array = qw/ happy sad worried /;

  my $html = <<EOT;
    <html>
      <head></head>
      <body>
        <select>
EOT

  foreach my $item (@array) {
    $html .= "<option value='$item'>$item</option>";
  }

  $html .= <<EOT;
        </select>
      </body>
    </html>
EOT

  return $html;
}

Disclaimer: It's very bad practice to mix other languages with Perl. If you are printing HTML you should use a templating system, which keeps the HTML in separate files and just plugs in the values of your data. I suggest not writing your own.

The way forward always starts with a minimal test.
