Echo mysql 会导致循环 - Echo mysql results in a loop?

我正在使用turn.js来制作一本书。"死亡笔记"div中的每个div都变成了新的一页。

<div id="deathnote"> //starts book
<div style="background-image:url(images/coverpage.jpg);"></div> //creates new page
<div style="background-image:url(images/paper.jpg);"></div> //creates new page
<div style="background-image:url(images/paper.jpg);"></div> //creates new page
</div> //ends book

我正在做的是尝试将 3 个"内容"（内容是名称和死因）divs到 1 页上，然后生成一个新页面。

所以这就是我想要的：

<div id="deathnote"> //starts book
<div style="background-image:url(images/coverpage.jpg);"></div> //creates new page
<div style="background-image:url(images/paper.jpg);"></div> //creates new page
<div style="background-image:url(images/paper.jpg);"> //creates new page but leaves it open
<div> CONTENT </div>
<div> CONTENT </div>
<div> CONTENT </div>
</div> //ends the page
    </div> //ends book

看起来很简单，但是内容是来自MySQL数据库的数据，所以我必须在使用PHP时回显它。这是我到目前为止所拥有的

<div id="deathnote">
    <div style="background-image:url(images/coverpage.jpg);"></div>
    <div style="background-image:url(images/paper.jpg);"></div>
    <div style="background-image:url(images/paper.jpg);"></div>
    <div style="background-image:url(images/paper.jpg);"></div>
    <div style="background-image:url(images/paper.jpg);"></div>
    <div style="background-image:url(images/paper.jpg);"></div>
        <?php
$pagecount = 0;
$db = new mysqli('localhost', 'username', 'passw', 'DB');
if($db->connect_errno > 0){
    die('Unable to connect to database [' . $db->connect_error . ']');
}
$sql = <<<SQL
    SELECT *
    FROM `TABLE`
SQL;
if(!$result = $db->query($sql)){
    die('There was an error running the query [' . $db->error . ']');
}
//IGNORE ALL OF THE GARBAGE ABOVE. IT IS SIMPLE CONNECTING SCRIPT THAT I KNOW WORKS
//THE METHOD I AM HAVING TROUBLE WITH IS BELOW
 $pagecount = 0;
while($row = $result->fetch_assoc()){ //GETS THE VALUE (and makes sure it isn't nothing
echo '<div style="background-image:url(images/paper.jpg);">'; //THIS OPENS A NEW PAGE
while ($pagecount !== 3) { //KEEPS COUNT OF HOW MUCH CONTENT DIVS IS ON THE PAGE
                        while($row = $result->fetch_assoc()){ 

//START A CONTENT DIV
echo '<div class="content"><div class="name">'  . $row['victim'] . '</div><div class="cod">'  . $row['cod'] . '</div></div>';
//END A CONTENT DIV
                            $pagecount++; //UP THE PAGE COUNT
                        }
                                                }
                        $pagecount=0; //PUT IT BACK TO 0
echo '</div>'; //END PAGE
}
$db->close();
?>
    <div style="background-image:url(images/backpage.jpg);"></div> //BACK PAGE
</div>

目前我似乎正在导致无限循环，因此页面无法加载。问题出在while循环中。

任何帮助将不胜感激。提前感谢伙计们。:)

请先在本地实例中运行以下代码，并确认下面是您的预期概念。之后，您可以更改结果集并让我知道，

  <?php 
       $Numbers = range(1, 25); // change your result set here 
       $Limit = 3;
       $i=0;
       foreach($Numbers as $number){
            if($i==$Limit){
                    echo "<hr>"; // new page
                    $i=0; // reset the limiter
            }
            echo $number; // Values to be displayed
            $i++;
        }             
      ?>

我已经为您重写了循环，循环现在遍历整个数据库，并在需要时放置开始div 和结束div。

<div id="deathnote">
<div style="background-image:url(images/coverpage.jpg);"></div>
<div style="background-image:url(images/paper.jpg);"></div>
<div style="background-image:url(images/paper.jpg);"></div>
<?php
$pagecount = 0;
$db = new mysqli('localhost', 'username', 'passw', 'DB');
if($db->connect_errno > 0){
    die('Unable to connect to database [' . $db->connect_error . ']');
}
$sql = <<<SQL
    SELECT *
    FROM `TABLE`
SQL;
if(!$result = $db->query($sql)){
die('There was an error running the query [' . $db->error . ']');
}
$pagecount=0;
while($row = $result->fetch_assoc()){
if($pagecount==0){ echo '<div style="background-image:url(images/paper.jpg);">';}
echo '<div class="content"><div class="name">'  . $row['victim'] . '</div><div class="cod">'  . $row['cod'] . '</div></div>';
if($pagecount==2){echo '</div>';}
$pagecount++;
if($pagecount==3){$pagecount=0;}
}
//this page count closes the last div (page) if you have less than three entries in it
if($pagecount==1||$pagecount==2){echo '</div>';}
$db->close();
?>
    <div style="background-image:url(images/backpage.jpg);"></div> //BACK PAGE
</div>
