PHP将mysql数据导出到excel表但在浏览器中显示

Question

我正在尝试将数据从 PHP mysql 导入到 Excel，并且运行良好。但是一旦我单击导入按钮，它就会显示在浏览器中。

header("Content-Disposition: attachment; filename=faculty-export.xls");
header("Content-type: application/vnd-ms-excel; charset=UTF-8;");

我已经在我的 PC(Windows 7、IIS、PHP 5.4)中进行了本地测试，其工作正常，但是当我在 Web 服务器(PHP 5.3、Linux、Apache 2.2.3)上上传时，导出数据显示在浏览器中(测试浏览器) IE 10、11、Firefox 和 Chrome)。

我遇到问题，因为我们必须更改服务器中的某些设置，或者我是否对编码中的某些内容进行了操作？

发布数据

 <form method="post" action="export_excel.php">
<input type="hidden" name="excel_name" value="<?php echo $_GET['name']; ?>">
<input type="hidden" name="excel_gender" value="<?php echo $_GET['gender']; ?>">
<input type="hidden" name="excel_college" value="<?php echo $ColName; ?>">
<input type="hidden" name="excel_department" value="<?php echo $_GET['deptf']; ?>">
<input type="hidden" name="excel_nationality" value="<?php echo $_GET['natf']; ?>">
<input type="hidden" name="excel_finalstatus" value="<?php echo $_GET['fstatusf']; ?>">
<input type="hidden" name="excel_fyear" value="<?php echo $_GET['fyearf']; ?>">
  <input style="float:left;" type="submit" value="Save to Excel">
</form>

下面是export_excel.php的代码。

<?php

    $query="select * from ab";

}
 else
    {
         $wheres = array();

          $query = "select * from ab where ";

嗨，我在这里改变了一些东西

<?php
$xls_filename = 'export_'.date('d-m-Y').'.xls'; // Define Excel (.xls) file name
header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");;
header("Content-Disposition: attachment;filename=$xls_filename");
header("Content-Transfer-Encoding: binary ");

include("connectdb.php");
$query="select * from ab WHERE 1=1 ";
if (isset($_POST['excel_name']) and !empty($_POST['excel_name']))
 {
  $query.= " AND name like '%{$_POST['excel_name']}%' ";
 }
if (isset($_POST['excel_gender']) and !empty($_POST['excel_gender']))
 {
  $query.= " AND gender = '{$_POST['excel_gender']}'";
 }
if (isset($_POST['excel_college']) and !empty($_POST['excel_college']))
 {
 $query.= " AND college = '{$_POST['excel_college']}' ";
 }
if (isset($_POST['excel_department']) and !empty($_POST['excel_department']))
 {

 }

 if (isset($_POST['excel_nationality']) and !empty($_POST['excel_nationality']))
 {

 }

if (isset($_POST['excel_finalstatus']) and !empty($_POST['excel_finalstatus']))
 {
  $query.= " AND finalstatus = '{$_POST['excel_finalstatus']}' ";
 }

if (isset($_POST['excel_fyear']) and !empty($_POST['excel_fyear']))
 {

 }
 $result = mysqli_query($conn,$query);

 echo "<table border='1'>

 while($res = mysqli_fetch_assoc($result)){

    while($row = mysqli_fetch_assoc($result1)) {
        echo "<td>".$row['DUName']."<br>".$row['DYEAR']."</td>";
    }
}
echo "</tr>";
}
echo "</table>";
exit();
?>

请在您的export_excel.php中使用此代码，如果发生错误，请告诉我
