There is no native function for this, but you can use the Holiday API, it supports holidays from Brazil and other locations, Portugal is not currently supported.

For demo I made this Javascript:

$(':button').click(function() {
  var dia = $(':input[dia]').val();
  var mes = $(':input[mes]').val();
  var ano = $(':input[ano]').val();
  var pais = $(':input[pais]').val();

  $.ajax({
    url: 'http://holidayapi.com/v1/holidays?country=' + pais + '&year=' + ano + '&month=' + mes + '&day=' + dia,
    type: "get",
    dataType: "json",
    success: function(data) {
      alert(data.holidays[0] != null ? data.holidays[0].name : 'Não é feriado');
    }
  });
});
input {
  width: 40px;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>


<table>
  <tr>
    <td>Data:</td>
    <td>
      <input dia value="21">/
      <input mes value="04">/
      <input ano value="2016">
    </td>
  </tr>
  <tr>
    <td>Local:</td>
    <td>
      <select pais>
        <option value="BR">BR</option>
        <option value="US">US</option>
        <option value="FR">FR</option>
        <option value="ES">ES</option>
      </select>
    </td>
  </tr>
</table>



<button>VERIFICAR</button>

For PHP you can use Curl:

   function verificarFeriado($data, $boolean = false) {

    $param = array();

    // Sua chave (exigida após 01/08/2016!), leia no final dessa postagem!
    $param['key'] = '';

    // Listas de países suportados!
    $paisesSuportados = array('BE', 'BG', 'BR', 'CA', 'CZ', 'DE', 'ES', 'FR', 'GB', 'GT', 'HR', 'HU', 'ID', 'IN', 'IT', 'NL', 'NO', 'PL', 'PR', 'SI', 'SK', 'US');

    // Define o pais para buscar feriados
    $param['country'] = $paisesSuportados[2];

    // Quebra a string em partes (em ano, mes e dia)
    list($param['year'], $param['month'], $param['day']) = explode('-', $data);

    // Converte a array em parâmetros de URL
    $param = http_build_query($param);

    // Conecta na API
    $curl = curl_init('https://holidayapi.com/v1/holidays?'.$param);

    // Permite retorno
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

    // Obtem dados da API
    $dados = json_decode(curl_exec($curl), true);

    // Encerra curl
    curl_close($curl); 

    // Retorna true/false se houver $boolean ou Nome_Do_Feriado/false se não houve $boolean
    return isset($dados['holidays']['0']) ? $boolean ? true : $dados['holidays']['0']['name'] : false;

    }

    var_export( verificarFeriado('2016-04-21') );
    // Resposta: 'Tiradentes'

    var_export( verificarFeriado('2016-04-21', true) );
    // Resposta: true

    var_export( verificarFeriado('2016-04-20') );
    // Resposta: false

    var_export( verificarFeriado('2016-04-20', true) );
    // Resposta: false

Important:

As of 01/08/2016 it will be necessary to get a key to the API, for this generate one, for free, through the site itself: https://holidayapi.com/.

From 01/08/2016 it will be necessary to use HTTPS instead of HTTP.

The function (in PHP) was updated on 07/12/2016 to support these API changes.
