PHP 隐藏真实下载地址

?

代码:

?

?

<?
	$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);
	}
?>
