Question

Web浏览器正在确定我生成的php生成的音频播放器有无效的来源。我也正在注意一下＆＃39; 0＆＃39;就在我的分页链接之前。

老实说，我不明白。我还在几个网络浏览器中检查了这些元素，它们看起来都在向我展示有效的HTML代码。

<?php 
    include_once("connect.php");
    $count_query =  mysqli_query($dbhandle,"SELECT NULL FROM my_audio");
    $count = mysqlI_num_rows($count_query);

    $previous_page = "'                  'Previous";
    $next_page = "Next ";
    //global $output;
    //pagination starts here
    if(isset($_GET['page']))
    {
        $page = preg_replace("#[^0-9]#","",$_GET['page']);
    }
    else
    {
        $page = 1;
    }

    $perPage = 5;
    $lastPage = ceil($count/$perPage);

    if($page <1)
    {
        $page =1;
    }
    else if($page>$lastPage)
    {
        $page = $lastPage;
    }

    $limit = "LIMIT ".($page - 1)*$perPage.",$perPage";
    //$limit = " LIMIT 0,1";
    $query = mysqli_query($dbhandle,"SELECT * FROM my_audio $limit");
    if($lastPage != 1)
    {
        $output = '';
        $pagination=0;
        if($page != $lastPage)
        {
            $next = $page + 1;
            $pagination.='<a href="sqltest1.php?page='.$next.'">'.$next_page.'</a>';
        }

        if($page != 1)
        {
            $prev = $page - 1;
            $pagination.='<a href="sqltest1.php?page='.$prev.'">'.$previous_page.'</a>';
        }

    }

    while($row = mysqli_fetch_array($query))
    {
        $sourcefile=$row['location'];
        **$output.='<audio controls="controls"><source src="'.$sourcefile.'" type="audio/mpeg"> Your browser does not support the audio tag.</audio><br><br>';
    }** 
?>

Answer 1

您正在将$pagination初始化为数值变量，其值为零而不是空字符串。这意味着当您将其与字符串连接时，它将以0为前缀。

变化：

$pagination=0;

为：

$pagination="";
