请问php如何让浏览器下载一个文本文件?
网友回复
<?php $content = "文本内容";//文件内容 header("Content-type: application/octet-stream"); header("Accept-Ranges: bytes"); header("Content-Disposition: attachment; filename = filename.txt"); //文件命名 header("Expires: 0"); header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); header("Pragma: public"); echo $content;
