PHP输出CSV文件出现乱码问题

问题:PHP输入用户列表为csv文件,用excel打开显示为乱码,用记事本或ue打开正常.查看文件编码显示为utf-8

 

解决:

function down_file($filepath,$filename)

{

if(!file_exists($filepath))

{

echo "backup error ,download file no exist";

exit();

}

ob_end_clean();

header('Content-Type: application/download');

header("Content-type: text/csv");

header('Content-Disposition: attachment;filename="'.$filename.'"');

header("Content-Encoding: binary");

  header("Content-Length:".filesize($filepath));

header("Pragma: no-cache");

header("Expires: 0");

readfile($filepath);

$e=ob_get_contents();

ob_end_clean();

}

 

$fname='usersdata.csv';

$handle=fopen($fname,'wb');

$strUsersData =iconv('utf-8','gb2312',$strUsersData);//转换编码

if(fwrite($handle,$strUsersData)==false){}

fclose($handle);

down_file($fname,'555.csv');
