use readfile()and application/octet-streamheaders
使用readfile()和application/octet-stream标题
<?php
$handle = fopen("file.txt", "w");
fwrite($handle, "text1.....");
fclose($handle);
header('Content-Type: application/octet-stream');
header('Content-Disposition: attachment; filename='.basename('file.txt'));
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
header('Content-Length: ' . filesize('file.txt'));
readfile('file.txt');
exit;
?>

$content = file_get_contents ($filename);
header ('Content-Type: application/octet-stream');
echo $content;
Should work
