Question

我正在为我的一个模块创建一个网站，每次我从数据库调用信息到页面上的所有html下面这个'内容div类'消失了，任何人都知道为什么??

以下是制作的php页面：

<link rel="stylesheet" href="css/productiontable.css">
<?php 
error_reporting(0);
require './db/connect.php';
include './includes/header.php'; 

?>
<h2>Productions</h2>

<div class="productiontable">
    <h3>What's on at this theatre</h3>
    <?php 
        if($result = $connection->query("SELECT * FROM Production")){
                        if($count = $result->num_rows){

                            while($row = $result->fetch_object()){
    ?>
    <div class="centredinfo">
        <div class="coloumns">
            <div class="productionname">
                <?php echo $row->ProductionName; ?>
            </div>
            <div class="productiontype">
                <?php echo $row->ProductionType; ?>
            </div>
            <div class=""></div>
            <div class="clear"></div>
        </div>
     </div>            

    <?php           }
    $result->free();
            }
    } 
    echo $result; 
    mysqli_close($connection);
    ?>

    <p>please click on productions for more info</p>
</div>               

<?php include './includes/footer.php'; ?>

这是整个网站的主要内容：

    margin: 10px;

    width: 600px;
    margin: 0 auto;
}
.coloumns div{
    width: 300px;
    float: left;
}

任何人都知道为什么？

我删除了error_reporting（0）;给我错误并显示echo $ result;导致问题，我已删除它，现在它完美地工作。非常感谢：）
