廢話不多說，直接上代碼

<?php  // 暫不支持斷點續傳  // $url = 'http://www.mytest.com/debian.iso'; 不知道為何獲取本地文件大小為0  $url = 'http://192.168.8.93/download/vm-672/18/0.vmdk';  $file = basename($url);  $header = get_headers($url, 1);  $size = $header['Content-Length'];  $fp = fopen($url, 'rb');  if ($fp === false) exit('文件不存在或打開失敗');  header('Content-Description: File Transfer');  header('Content-Type: application/octet-stream');  header('Content-Disposition: attachment; filename="'.$file.'"');  header('Content-Transfer-Encoding: binary');  header('Expires: 0');  header('Cache-Control: must-revalidate, post-check=0, pre-check=0');  header('Pragma: public');  header('Content-Length: ' . $size);  ob_clean();  ob_end_flush();  set_time_limit(0);    $chunkSize = 1024 * 1024;  while (!feof($fp)) {    $buffer = fread($fp, $chunkSize);    echo $buffer;    ob_flush();    flush();  }  fclose($fp);  exit;
