php 다운로드 저장 파일을 로컬에 저장하는 두 가지 실현 방법

첫 번째:

<?php 
function downfile()
{
 $filename=realpath("resume.html"); // 
 $date=date("Ymd-H:i:m");
 Header( "Content-type:  application/octet-stream "); 
 Header( "Accept-Ranges:  bytes "); 
Header( "Accept-Length: " .filesize($filename));
 header( "Content-Disposition:  attachment;  filename= {$date}.doc"); 
 echo file_get_contents($filename);
 readfile($filename); 
}
downfile();
?>

또는

<?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);
}
 $url="url ";
 downfile($url);
?> 

두 번째:

<?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); 
}
$url="url ";
downfile($url);
?>

PHP에서 파일을 다운로드하는 두 가지 방법입니다.나눠서 쓸모 있는 친구를 만나보세요.
방법 1:

<?php
/**
*  
* header 
*
*/
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);
?>

php에서header 함수의 용법을 이해합니다.
방법 2:

<?php
// 
//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();
?>
