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();?>
