php - 写一个文本文件并用php强制下载

Question

我使用按钮指向创建文本文件的脚本：

<?php
$handle = fopen("file.txt", "w");
fwrite($handle, "text1.....");
fclose($handle);
?>

之后我希望网络浏览器建议下载或打开这个文件我应该怎么做？谢谢

Answer 1

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;
?>

Answer 2

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

应该管用
