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();
?>
