$file_name = "info_check.exe";

$file_dir = "/public/www/download/";

//检查文件是否存在

if(!file_exists($file_dir . $file_name)) exit('文件找不到');

else

{

$file = fopen($file_dir . $file_name,"r"); // 打开文件

// 输入文件标签

Header("Content-type: application/octet-stream");

Header("Accept-Ranges: bytes");

Header("Accept-Length: ".filesize($file_dir . $file_name));

Header("Content-Disposition: attachment; filename=" . $file_name);

// 输出文件内容

echo fread($file,filesize($file_dir . $file_name));

fclose($file);

exit;

}

而如果文件路径是“http”或者“ftp” 网址的话，则源代码会有少许改变，程序如下：

$file_name = "info_check.exe";

$file_dir = "http://www.easycn.net/";

$file = @ fopen($file_dir . $file_name,"r");

if (!$file) exit('文件找不到');

else {

Header("Content-type: application/octet-stream");

Header("Content-Disposition: attachment; filename=" . $file_name);

while (!feof ($file)) {

echo fread($file,50000);

}

fclose ($file);

}
