Get data from SQL Database in PHP for a table

Question

EDIT : Using mysql_connect in PHP 7 . Solved .

I've try to make a table with the last entry in my Database, so i've try to get my last 5 data and repeat it in a table.

This is the structure of my Database:

CREATE TABLE `submitph` (
  `id` int(11) NOT NULL,
  `phrase` text NOT NULL,
  `mode` varchar(255) NOT NULL,
  `enable` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;

And my php code

<tbody>
                        <?php
                        mysql_connect("localhost", "root", "root");
                        mysql_select_db("jnj");
                            $retour = mysql_query('SELECT * FROM submitph ORDER BY id DESC LIMIT 0,5');
                            while ($donnees = mysql_fetch_array($retour))
                            {
                        ?>
                        <tr>
                          <td>
                            <?php echo stripslashes($donnees['id']); ?>
                          </td>
                          <td>
                            <?php 
                                 $phrase = nl2br(stripslashes($donnees['phrase']));
                                 echo $phrase;
                            ?>
                          </td>
                          <td>
                            <a href="">Approuver</a> / <a href="">Refuser</a>
                          </td>

                        </tr>
                        <?php
}    ?>

                      </tbody>

But i didn't have any data in my table, i didn't have any php error, didn't understand why. Did i miss something ?

EDIT 1 (All my table) :

       <table class="table table-hover">
                      <thead class="">
                                <th>
                          ID
                        </th>
                        <th>
                          Phrase
                        </th>
                        <th>
                          Status
                        </th>

                      </thead>
                      <tbody>
                                            <?php
                        mysql_connect("localhost", "root", "root");
                        mysql_select_db("jnj");
                            $retour = mysql_query('SELECT * FROM submitph ORDER BY id DESC LIMIT 0,5');
                            while ($donnees = mysql_fetch_array($retour))
                            {
                        ?>
                        <tr>
                          <td>
                            <?php echo stripslashes($donnees['id']); ?>
                          </td>
                          <td>
                            <?php 
                                 $phrase = nl2br(stripslashes($donnees['phrase']));
                                 echo $phrase;
                            ?>
                          </td>
                          <td>
                            <a href="">Approuver</a> / <a href="">Refuser</a>
                          </td>

                        </tr>
                        <?php
} 
?>

                      </tbody>
                    </table>

EDIT 2 : SQL Data

INSERT INTO `submitph` (`id`, `phrase`, `mode`, `enable`) VALUES
(3, 'Test1', 'Hard', 0),
(5, 'Test2', 'Soft', 0),
(6, 'Test3', 'Hard', 0);

Answer 1

您没有将$ connection变量传递给mysql_query（）;
