使用 PHP 限制下载速度
2022-08-30 23:10:43
我在Google上发现了一些PHP脚本来限制文件的下载速度,但是文件下载速度为10 Mbps,或者如果它以80 kbps的速度下载,则在我设置时,在5 mb之后,它将停止下载。
有人可以告诉我在哪里可以找到一个好的PHP下载速度限制脚本吗?
谢谢

代码如下:
<?php
set_time_limit(0);
// change this value below
$cs_conn = mysql_connect('localhost', 'root', '');
mysql_select_db('shareit', $cs_conn);
// local file that should be send to the client
$local_file = $_GET['file'];
// filename that the user gets as default
$download_file = $_GET['file'];
// set the download rate limit (=> 20,5 kb/s)
$download_rate = 85;
if(file_exists($local_file) && is_file($local_file)) {
// send headers
header('Cache-control: private');
header('Content-Type: application/octet-stream');
header('Content-Length: '.filesize($local_file));
header('Content-Disposition: filename='.$download_file);
// flush content
flush();
// open file stream
$file = fopen($local_file, "r");
while(!feof($file)) {
// send the current file part to the browser
print fread($file, round($download_rate * 1024));
// flush the content to the browser
flush();
// sleep one second
sleep(1);
}
// close file stream
fclose($file);}
else {
die('Error: The file '.$local_file.' does not exist!');
}
if ($dl) {
} else {
header('HTTP/1.0 503 Service Unavailable');
die('Abort, you reached your download limit for this file.');
}
?>
