所以我正在测试我的代码，本质上是我向数据库中插入一些信息，然后按时间顺序在数组中读取它，因此首先查看插入的最新内容。

问题：插入新数据但由于某种原因出现在网站的4位置，找不到异常。

这是插入查询：

<?php
//values to be inserted in database table
//session_start();
include('connect.php');


$title = $_POST['title'];
$tip= $_POST['tip'];

$query = "INSERT INTO tips (title, paragraph) VALUES(?, ?)";
$statement = $mysqli->prepare($query);

//bind parameters for markers, where (s = string, i = integer, d = double,  b = blob)
$statement->bind_param('ss', $title, $tip);

if($statement->execute()){
     print 'Success! ID of last inserted record is : ' .$statement->insert_id .'<br />'; 
     echo'<a href="membership.php" class="blar">Membership page</a>';
}else{
     die('Error : ('. $mysqli->errno .') '. $mysqli->error);
}
$statement->close();
?>

这是读取数据的代码：

$category = array(
    "dates" => array(),
    "paragraphs" => array(),
    "titles" => array()
);

if ($result = $mysqli->query("SELECT * FROM tips")){
    if($result->num_rows){
        while($row = $result->fetch_array(MYSQLI_ASSOC)){
        //printf ("%s %s %s\n",$row["date"], $row["title"], $row["paragraph"]); 
        $date[] = $row['date'];
        $paragraphs[] = $row['paragraph'];
        $titles[] = $row['title'];
        }
        }
        $result->free();
    }
?>

那么这种东西就按顺序来读吧：

<div class="cd-timeline-block">
            <div class="cd-timeline-img cd-picture">
                <img src="img/cd-icon-location.svg" alt="Location">
            </div> <!-- cd-timeline-img -->

            <div class="cd-timeline-content">
                <h2><?php echo $titles[count($titles)-1]?> </h2>
                <p><?php echo $paragraphs[count($paragraphs)-1]?></p>

                <span class="cd-date"><?php echo $date[count($date)-1]?></span>
            </div> <!-- cd-timeline-content -->
        </div> <!-- cd-timeline-block -->

        <div class="cd-timeline-block">
            <div class="cd-timeline-img cd-movie">
                <img src="img/cd-icon-location.svg" alt="Location">
            </div> <!-- cd-timeline-img -->

            <div class="cd-timeline-content">
                <h2><?php echo $titles[count($titles)-2]?></h2>
                <p><?php echo $paragraphs[count($titles)-2]?></p>

                <span class="cd-date"><?php echo $date[count($titles)-2]?></span>
            </div> <!-- cd-timeline-content -->
        </div> <!-- cd-timeline-block -->

这是前两个数组，不明白异常在哪里，有指针吗？
