Question

编辑：感谢您更正格式...没有注意到错误

我已经完成了这个基本报价生成器作为第一个项目，但是注意到它经常在刷新时显示相同的报价。当然，目前只有五个，但是当我填满数据库时，可能这个问题仍然很明显。我目前正在学习更高级的JQuery AJAX - 但我才开始。据我所知，这不是一个重复的问题。重新加载时显示数据库查询。谢谢！这是代码：

connect.php：

<?php

$connection = new mysqli('localhost', 'root', '', 'random_quotes');

if ($connection->connect_error) {
    die('Connect Error (' . $mysqli->connect_errno . ')'
        . $mysqli->connect_error);
}
?>

的functions.php：

<?php
require ('connect.php');
$query = "SELECT id, quote, author FROM quotes ORDER BY RAND() LIMIT 1";
    $getQuote = $connection->query($query);
?>

HTML：

<!doctype html>
<html lang="en">

<?php
require ('includes/connect.php');
require ('includes/functions.php');
?>

    <br/>
    <button class="btn btn-default" onclick="newQuote()" type="submit">New Quote
    </button>
    <div class="quote_wrap text-center">
        <span class="quote">
            <?php
            while($row = $getQuote->fetch_assoc()){
                $stringID = $row['id'];
                $stringQuote = $row['quote'];
                $stringAuthor = $row['author'];
                echo $stringQuote;
                }
              ?>
        </span>
      </br>
      <div class="author text-center"><?php echo $stringAuthor?></div>
      <div class="quoteid" id="<?php echo $stringID?>"></div>
    </div>

生成随机数，然后按该ID访问引号。可能会更好..

    $query = "SELECT COUNT(*) as noQuotes FROM quotes ";
    $result = $connection->query($query);
    $row = $result->fetch_assoc();

    $noQuotes = $row["noQuotes"];

    srand(time());
    //echo(rand(1,$noQuotes));
    $randNo = rand(1,$noQuotes);


    $query = "SELECT id, quote, author FROM quotes WHERE id = $randNo ";
    $getQuote = $connection->query($query);

PHP基本随机报价生成器。如何防止最近出现的报价？
