通过php表单下载后数据损坏

php mysql session

通过php表单下载后数据损坏,php,mysql,session,Php,Mysql,Session,下载时，我的输出应包含以下内容： <?php global $table; global $act; global $upload; if(!isset($_SESSION)) { session_start(); } include('db_connection.php'); if(isset($_POST['choose_lang'])) { $table = $_POST['choose_lang']; } if(isset($_POST['actio

下载时，我的输出应包含以下内容：

<?php
global $table;
global $act;
global $upload;

if(!isset($_SESSION)) 
{ 
    session_start(); 
}
include('db_connection.php');

if(isset($_POST['choose_lang']))
{ 
    $table = $_POST['choose_lang'];
 } 
if(isset($_POST['action']))
{
    $act = $_POST['action'];
    }
if(isset($_GET['upload']))
{
    $upload = $_GET['upload'];
    }
$upload = $_GET['upload'];

$_SESSION['upload'] = $upload;

$table = $_SESSION['choose_lang'];
$act=$_SESSION['action'];

   $query = "SELECT  *   FROM  $table WHERE upload = '".$_SESSION['upload']."' AND    category = '$act'" ;

 $result = mysql_query($query);
 $row = mysql_fetch_array($result, MYSQL_BOTH);
 $size = $row['filesize1'];

 $type = $row['filetype1'];
 $name =$row['filexml'];

 $text = $row['data1'];

 header("Content-length:".$size);
 header("Content-type:".$type);
 header("Content-Transfer-Encoding: Binary");
 header("Content-Disposition: attachment; filename=".$name);
 readfile("$text");
 echo $text;
 ?>

相反，当打开时，输出以记事本文件的形式出现：

   File type = "ooTextFile"
   Object class = "TextGrid"

   xmin = 0 
   xmax = 2.264331065759637 
   tiers? <exists> 
   size = 1 
   item []: 
   item [1]:
    class = "IntervalTier" 
    name = "vowels" 
    xmin = 0 
    xmax = 2.264331065759637 
    intervals: size = 5 
    intervals [1]:
        xmin = 0 
        xmax = 0.9286507897337561 
        text = "" 
    intervals [2]:
        xmin = 0.9286507897337561 
        xmax = 1.0970767840615319 
        text = "a" 
    intervals [3]:
        xmin = 1.0970767840615319 
        xmax = 1.2213912084463185 
        text = "" 
    intervals [4]:
        xmin = 1.2213912084463185 
        xmax = 1.447964272244398 
        text = "e" 
    intervals [5]:
        xmin = 1.447964272244398 
        xmax = 2.264331065759637 
        text = ""

因此，我的文件被损坏。错误在哪里。请帮忙！！！！HTML主体来自哪里。

您可能有自动包含的锅炉板。从哪里调用此脚本？从php表单下载此textgrid文件。您发布的php脚本是表单的操作，我理解对吗？boiler plate只是指从某处复制的标准文本。非常感谢TIM是的，prblm与db_连接在一起。phpThnx TIM解决了html来自db_连接。php它是垃圾！！！！
