第一种：

<?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

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

第二种：

<?php function downfile($fileurl) { $filename=$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：

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