我正在使用mssql server和CI,它将db文件自动备份到某个文件夹中,现在我需要让用户将文件从服务器下载到本地计算机。
$filename = basename($_GET['file']);
// Specify file path.
$path = 'backups/hello.txt';
$download_file = $path.$filename;
if(!empty($filename)){
// Check file is exists on given path.
if(file_exists($download_file))
{
header('Content-Disposition: attachment; filename=' . $filename);
readfile($download_file);
exit;
}
else
{
echo 'File does not exists on given path';
}
}
}
我试过这个,但它说文件不详。
答案 0 :(得分:2)
根据php文档,你能尝试这样吗
<强>的download.php 强>
if (file_exists($file)) {
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');//change your extension of your files
header('Content-Disposition: attachment; filename="'.basename($file).'"');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize($file));
readfile($file);
exit;
}
