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();?>
