单纯的下载功能实现
<?php
// 表示调用文本类型为pdf的应用
header('Content-type: application/pdf'); // 这句可以输出下载页面进行下载
header('Content-Disposition: attachment; filename="downloaded.pdf"'); // 能够读出pdf
readfile('original.pdf');
?>
实现各种文件的下载方法：
<?php $file="N1.PDF"; downloadFile($file);
function downloadFile( $fullPath ){ // Must be fresh start
if( headers_sent() )
die('Headers Sent'); // Required for some browsers
if(ini_get('zlib.output_compression'))
ini_set('zlib.output_compression', 'Off'); // File Exists?
if( file_exists($fullPath) ){ // Parse Info / Get Extension
$fsize = filesize($fullPath);
$path_parts = pathinfo($fullPath);
$ext = strtolower($path_parts["extension"]); // Determine Content Type
switch ($ext) {
case "pdf": $ctype="application/pdf"; break;
case "exe": $ctype="application/octet-stream"; break;
case "zip": $ctype="application/zip"; break;
case "doc": $ctype="application/msword"; break;
case "xls": $ctype="application/vnd.ms-excel"; break;
case "ppt": $ctype="application/vnd.ms-powerpoint"; break;
case "gif": $ctype="image/gif"; break;
case "png": $ctype="image/png"; break;
case "jpeg":
case "jpg": $ctype="image/jpg"; break;
default: $ctype="application/force-download";
} header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: $ctype");
header("Content-Disposition: attachment; filename=\"".basename($fullPath)."\";" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".$fsize);
ob_clean();
flush();
readfile( $fullPath ); } else
die('File Not Found'); } ?>
PHP 扒网页资源 ，测试能扒网页和ZIP 只是要想办法知道格式
<?php
$file="http://www.yinghy.com/index.php";
header("Pragma: public"); // required
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0");
header("Cache-Control: private",false); // required for certain browsers
header("Content-Type: application/force-download");
header("Content-Disposition: attachment; filename=\"index.html\"" );
header("Content-Transfer-Encoding: binary");
header("Content-Length: ".filesize("index.php"));
ob_clean();
flush();
readfile($file);
?>
