Question

<?php
$month=$_REQUEST["month"];
include 'include/myfunc.php';
$sql = "SELECT * FROM announcement WHERE month='".$month."'";
$result = mysqli_query($con,$sql);
$status="";
$html='<table><tr><td>Date</td><td>Announcement Detail</td><td>Tag</td><td>Amount</td><td>Status</td><td>File Name</td></tr>' ;

while( $row = mysqli_fetch_array($result) )
{
    if ($row['status']=="active") {
      $status = "निरकर्त";
    }else{
        $status = "लंबित";
    }

    $html.='<tr><td>'.$row['date'].' '.$row['month'].' '.$row['year'].'</td><td>'.$row['announcement_detail'].'</td><td>'.$row['tag'].'</td><td>'.$row['amount'].'</td><td>'.$status.'</td><td>'.$row['file'].'</td></tr>' ;

header('Content-Disposition:attachment;filename=report.xls');

不是执行回声，而是像这样转换它，它将起作用。

print chr(255) . chr(254) . mb_convert_encoding($html, 'UTF-16LE', 'UTF-8');
