我正在尝试将MySQL数据保存到Excel文件，但是Excel单元格出现问题。我所有的文本都放在一个单元格中，我希望每个行值都在单独的Excel单元格中。这是我的代码：

$queryexport = ("
SELECT username,password,fullname FROM ecustomer_users
WHERE fk_customer='".$fk_customer."'
");
$row = mysql_fetch_assoc($queryexport);
$result = mysql_query($queryexport);
$header = '';
for ($i = 0; $i < $count; $i++){
   $header .= mysql_field_name($result, $i)."\t";
   }
while($row = mysql_fetch_row($result)){
   $line = '';
   foreach($row as $value){
          if(!isset($value) || $value == ""){
                 $value = "\t";
          }else{
                 $value = str_replace('"', '""', $value);
                 $value = '"' . $value . '"' . "\t";
                 }
          $line .= $value;
          }
   $data .= trim($line)."\n";
   $data = str_replace("\r", "", $data);
if ($data == "") {
   $data = "\nno matching records found\n";
   }
}
header("Content-type: application/vnd.ms-excel; name='excel'");
header("Content-Disposition: attachment; filename=exportfile.xls");
header("Pragma: no-cache");
header("Expires: 0");
// output data
echo $header."\n".$data;
mysql_close($conn);`
