php断点续传 [复制链接]

一个例子：
$fname = './05e58c19552bb26b158f6621a6650899';
$fp = fopen($fname,'rb');
$fsize = filesize($fname);
if (isset($_SERVER['HTTP_RANGE'])
&& ($_SERVER['HTTP_RANGE'] != "")
&& preg_match("/^bytes=([0-9]+)-$/i", $_SERVER['HTTP_RANGE'], $match)
&& ($match[1] < $fsize))
{
$start = $match[1];
}
else
{
$start = 0;
}
@header("Cache-control: public");
@header("Pragma: public");
if ($start > 0)
{
fseek($fp, $start);
Header("HTTP/1 dot 1 206 Partial Content");
Header("Content-Length: " . ($fsize - $start));
Header("Content-Ranges: bytes" . $start . "-" . ($fsize - 1) . "/" . $fsize);
}
else
{
header("Content-Length: $fsize");
Header("Accept-Ranges: bytes");
}
@header("Content-Type: application/octet-stream");
@header("Content-Disposition: attachment;filename=1.rm");
fpassthru($fp);
