第一種：<?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);

?>

第二種：<?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實(shí)現(xiàn)下載文件的兩種方法。分享下，有用到的朋友看看哦。

方法一：<?php

/**

* 下載文件

* header函數(shù)

*

*/

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函數(shù)的用法。

方法二：<?php

//文件下載

//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();

?>
