php 下载保存文件保存到本地的两种实现方法

这里的下载，指的是 弹出下载提示框。

第一种：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14

<?php function downfile() {  $filename=realpath("resume.html"); //文件名  $date=date("Ymd-H:i:m");  Header( "Content-type:  application/octet-stream ");  Header( "Accept-Ranges:  bytes "); Header( "Accept-Length: " .filesize($filename));  header( "Content-Disposition:  attachment;  filename= {$date}.doc");  echo file_get_contents($filename);  readfile($filename); } downfile(); ?>

或 （推荐这种方法，亲测可行，其他的没测试）

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

<?php function downfile($fileurl) {  ob_start();  $filename=$fileurl;  $date=date("Ymd-H:i:m");  $size=readfile($filename);  header( "Content-type:  application/octet-stream ");  header( "Accept-Ranges:  bytes ");  header( "Content-Disposition:  attachment;  filename= {$date}.doc");   header( "Accept-Length: " .$size); }  $url="url地址";  downfile($url); ?>

第二种：

<?php function downfile($fileurl) { $filename=$fileurl; $file  =  fopen($filename, "rb"); Header( "Content-type:  application/octet-stream "); Header( "Accept-Ranges:  bytes "); Header( "Content-Disposition:  attachment;  filename= 4.doc"); $contents = ""; while (!feof($file)) {  $contents .= fread($file, 8192); } echo $contents; fclose($file); } $url="url地址"; downfile($url); ?>

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：

?

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17

<?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：

?

1 2 3 4 5 6 7 8 9 10

<?php //文件下载 //readfile $fileinfo = pathinfo($filename); header('Content-type: application/x-'.$fileinfo['extension']); header('Content-Disposition: attachment; filename='.$fileinfo['basename']); header('Content-Length: '.filesize($filename)); readfile($thefile); exit(); ?>
