require 'db.php';
 $q= mysql_query("select firstname,lastname,email from  tab_Recruiter where status=1");

header('Content-Type: text/csv; charset=utf-8');
header('Content-Disposition: attachment; filename=Userinfo.csv');
header("Pragma: no-cache"); 
header("Expires: 0");

$data = fopen('php://output', 'w');
$first = true;
 while($row = array_filter(mysql_fetch_assoc($q))){
 if ($first) {
        fputcsv($data, array_keys($row));
        $first = false;
   // fputcsv($fp, $row);
fputcsv($data, $row);

我在php中使用了下载mysql数据到csv的代码。在localhost中工作正常。当我点击 导出按钮它以csv格式在localhost下载文件,但是当我在服务器上运行此代码时,当我单击导出按钮时,它会打印它没有下载文件的数据。

 &lt; form method =“post”&gt; 
&lt; input type =“submit”name =“export”value =“export”&gt; 
&lt; / form&gt  ; 
if(isset($ _ POST ['export'])){
 $ q = mysql_query(“select firstname,lastname,来自tab_Recruiter的电子邮件,其中status = 1”  ); 
header('Content-Type:text / csv; charset = utf-8'); 
header('Content-Disposition:attachment; filename = Userinfo.csv'); 
header(“Pragma:no- 缓存“);  
 $ data = fopen('php:// output','w'); 
 $ first = true; 
 while($ row = array_filter(mysql_fetch_assoc(  $ q))){
 if($ first){
 fputcsv($ data,array_keys($ row)); 
 $ first = false; 
 // fputcsv($ fp,$ row)  ; 
fputcsv($ data,$ row);

    Chances of errors:

    • Your config may be different on the server.
    • <?php and header() should be the first calls within the page.

    Also, do not DOWNLOAD immediately with headers. For debugging purpose, disable your header() calls and see the output in the screen - if it contains errors.

    Only if it works correctly, set the headers correctly to force a download.
