每秒执行一次while循环

Question

I got this while loop that is displaying as you can see a username and a message which the user types... But after the message has been typed the user have to reload my page to see it. Is there a way to make the while loop execute while im on the site to keep it constantly updated?! like setting it to execute every second or something?

        <?php 
include "connect.php";
$query = "SELECT * FROM messages";
$result = $con->query($query);

if($result){

            while($row = $result->fetch_object()) 
            {
                echo "<ul id = 'rutor'>";
                echo '<li class = "userlada">'.$row->username. "</li>";
                echo '<li class = "usertext">'.$row->message. "</li>";
                echo "</ul>";
            }

}
?>

I'm not the brigetest on php so any help would be great!:)

No.

PHP is server-side, so if you start waiting and looping there, you'll just make the browser wait for it to be done.

For this you need to look into Javascript.
