Homephp教程php手册php使浏览器直接下载pdf文件的方法

本文介绍如何让用户打开pdf文件时不是直接在浏览器浏览而是直接以下载文件形式把pdf文件下载到电脑

有的浏览器安装了pdf打开程序关联到浏览器,所以直接写上pdf路径时是打开pdf而不是下载,下面我就说下如果让他们只是下载,而不是浏览。

创建一个php文件

复制代码 代码如下:


$file = $_GET['file'];
$arr = explode('/',$file);
header('Content-type: application/pdf');
header('Content-Disposition: attachment; filename="'.array_pop($arr).'"');
readfile(file);
?>
 



加入代码,,通过这个把pdf路径转换成浏览器认识的语言,告诉浏览器
列子 /upload.php?file=/aa/aa.pdf
这样就可以不管是什么,都会下载,而不是打开
