Displaying date in wrong language

I already tried the following code in php and did not work:

setlocale(LC_ALL, 'pt_BR.UTF-8', 'Portuguese_Brazil.1252');

My server apache is in centos and is running php 7.

You are displaying a date that comes from the English database: 01-SEP-2018 and the right is '01 -09-2018 '

I have already used the function DateTime and it resolves, however when it comes null , it displays the current date.

Should I update the language packs of centos ?

                               <?php

                             setlocale(LC_ALL, "pt_BR", "pt_BR.iso-8859-1", 
                              "pt_BR.utf-8", "portuguese");
                             date_default_timezone_set('America/Sao_Paulo');

                                    $datapagamento = $ct['DATA'];
                             ?>

                              <tr>
                                <td><?php echo $datapagamento; ?></td>
                                <td>

The array $ct is populated with a return of a sql from the database.
