php下载保存文件保存到本地的两种方法。

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 
//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：

<?php 
//下载文件保存至本地
//www.jbxue.com
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)) {
