解析PHP实现下载文件的两种方法

本篇文章是对使用PHP实现下载文件的两种方法进行了详细的分析介绍,需要的朋友参考下

方法一:

复制代码 代码如下:

header('Content-Description: File Transfer');

header('Content-Type: application/octet-stream');

header('Content-Disposition: attachment; filename='.basename($filepath));

header('Content-Transfer-Encoding: binary');

header('Expires: 0′);

header('Cache-Control: must-revalidate, post-check=0, pre-check=0′);

header('Pragma: public');

header('Content-Length: ' . filesize($filepath));

readfile($file_path);

方法二:

复制代码 代码如下:

$fileinfo = pathinfo($filename);

header('Content-type: application/x-'.$fileinfo['extension']);

header('Content-Disposition: attachment; filename='.$fileinfo['basename']);

header('Content-Length: '.filesize($filename));

readfile($thefile);

exit();
