php 下载保存文件保存到本地的两种方法

第一种：

1 <?php 2 function downfile()
3 {
4 $filename=realpath("resume.html"); //文件名
5 $date=date("Ymd-H:i:m");
6 Header( "Content-type: application/octet-stream ");
7 Header( "Accept-Ranges: bytes ");
8 Header( "Accept-Length: " .filesize($filename));
9 header( "Content-Disposition: attachment; filename= {$date}.doc");
10 echo file_get_contents($filename);
11 readfile($filename);
12 }
13 downfile();
14 ?>

或

<?php
//下载文件保存到本地
//www.jbxue.com
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：

1 <?php 2 //下载文件保存至本地
3 //www.jbxue.com
4 function downfile($fileurl)
5 {
6 $filename=$fileurl;
7 $file = fopen($filename, "rb");
8 Header( "Content-type: application/octet-stream ");
9 Header( "Accept-Ranges: bytes ");
10 Header( "Content-Disposition: attachment; filename= 4.doc");
11 $contents = "";
12 while (!feof($file)) {
13 $contents .= fread($file, 8192);
14 }
15 echo $contents;
16 fclose($file);
17 }
18 $url="url地址";
19 downfile($url);
20 ?>
