下载
分两种情况,一是文件单独下载:
<?
$file_name = "abc.exe";
$file_dir = "/xxx/";
if (!file_exists($file_dir . $file_name)) { //检查文件是否存在
echo "文件找不到";
exit;
} 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;}
?>
另外一种情况是文件路径包含“http”或者“ftp”网址:
<?
$file_name = "abc.exe";
$file_dir = "http://www.xrss.cn/";
$file = @ fopen($file_dir . $file_name,"r");
if (!$file) {
echo "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);
}
?>
