php回显第一行等待/ sleep 然后回显第二行

Question

我想知道有没有办法从数据库中的表中回显第一行等待/休眠 5 秒，然后回显第二行？

预先感谢您的帮助!

$conn = mysqli_connect('localhost', 'root', '','database');
$strSql=$conn->query("SELECT words FROM load ORDER BY id ASC ");
if($strSql->num_rows >0) {
    while ($row = $strSql->fetch_assoc()) {
    $rows[]=$row;
    foreach($rows as $row){
       $words1=$row['words'];
               echo '<div class="animatedText"> '.$words1.'</div>';
       //let's say sleep(5); and then print second row???
       }
   }
}

尝试使用 output buffering .例如:

header( 'Content-type: text/html; charset=utf-8' );

while ($row = $strSql->fetch_assoc()) {
      $rows[]=$row;
       foreach($rows as $row){
            $words1=$row['words'];
            echo '<div class="animatedText"> ';
            echo $words1;
            echo '</div>';
            flush();
            ob_flush();
            sleep(5);
           }
       }
