I corrected the code. Thank you for the help.

Code:
<?php 


$db_server = '127.0.0.1'; 
$db_user = 'fwhphp_user'; 
$db_password = 'k5BJRaX6SFbs'; 
$db_name = 'fwhphp_db'; 


$mysqli = new mysqli($db_server, $db_user, $db_password, $db_name); 


if ($mysqli->connect_errno) { 
    echo 'Connect failed: ' . $mysqli->connect_error; 
    exit(); 
} 


$sql = 'SELECT * FROM `chat`'; 
$result = $mysqli->query($sql); 


echo '<p>MySQL have returned ' . $result->num_rows . ' records.</p>'; 


echo '<br>'; 
echo '<hr>'; 


while ($chat = $result->fetch_object()) {
    echo '<b>' .  $chat->name . '</b> says : ' . $chat->message;
    echo '<br>';
    echo '<hr>';
}
