PHP简单实现断点续传下载的方法
本文实例讲述了PHP实现断点续传下载的方法。分享给大家供大家参考。具体如下:
$fname = 'http://XXXX/MMLDZG.mp3'; $fp = fopen($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 { $start = 0; } @header("Cache-control: public"); @header("Pragma: public"); if ($star--> 0) { fseek($fp, $start); Header("HTTP/1.1 206 Partial Content"); Header("Content-Length: " . ($fsize - $start)); Header("Content-Ranges: bytes" . $start . "-" . ($fsize - 1) . "/" . $fsize); } else { header("Content-Length: $fsize"); Header("Accept-Ranges: bytes"); } @header("Content-Type: application/octet-stream"); @header("Content-Disposition: attachment;filename=mmdld.mp3"); fpassthru($fp); fpassthru();//函数输出文件指针处的所有剩余数据。
该函数将给定的文件指针从当前的位置读取到 EOF,并把结果写到输出缓冲区。
希望本文所述对大家的php程序设计有所帮助。
