Header( "Accept-Ranges:  bytes ");
Header( "Accept-Length: " .filesize($filename));
header( "Content-Disposition:  attachment;  filename= {$date}.doc");

header( "Content-Disposition:  attachment;  filename= {$date}.doc");
$size=readfile($filename);
header( "Accept-Length: " .$size);
}
$url="url地址";
downfile($url);

第⼆种：
<?php
function downfile($fileurl)
{

PHP实现下载⽂件的两种⽅法。分享下，有⽤到的朋友看看哦。
⽅法⼀：
<?php
/**
* 下载⽂件
* header函数
*
*/
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($file_path);
>
了解php中header函数的⽤法。
⽅法⼆：
<?php
//⽂件下载
//readfile
php中header是什么意思$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();
