您好，我是snikolov我正在创建一个带有PHP的miniwebserver，我想知道如何发送客户端文件下载与他的浏览器如Firefox或Internet浏览器我发送文件给用户通过套接字下载，但是cleint没有得到文件名和下载的信息，请你在这里帮助我，如果我再次声明文件我在服务器中收到此错误
致命错误：无法重新声明openfile（）（之前在C：\ User中声明 s \ fsfdsf \ sfdsfsdf \ httpd.php：31）在 C：\ Users \ hfghfgh \ hfghg \ httpd.php 上的li ne 29
，如果有可能，我想知道网络服务器是否可以通过套接字显示用户请求的banwdidth，perl与php有相同的选项，但它比php更硬核不太了解perl，我甚至看到一个miniwebserver可以显示很多客户端用户从服务器拉出来有可能你可以帮助我编码，我非常感谢你们，谢谢你们。

Answer 1

您没有将文件名发送到客户端，那么它应该如何知道要使用哪个文件名？

有一个缺点，你可以在http标头中提供所需的文件名，但有些浏览器会忽略它，并始终根据URL中的最后一个元素建议文件名。例如，http://localhost/download.php?help.me将导致文件下载对话框中出现文件名为help.me的文件。

请参阅：http://en.wikipedia.org/wiki/List_of_HTTP_headers

Answer 2

每次运行while (1)循环时，都会声明openfile函数。您只能声明一次函数。尝试将openfile声明移到循环外。

  $httpsock = @socket_create_listen("9090");
  if (!$httpsock) {
    print "Socket creation failed!\n";
    exit;
  }
  while (1) {
    $client = socket_accept($httpsock);
    $input = trim(socket_read ($client, 4096));


    $input = explode(" ", $input);

    $input = $input[1];

    $fileinfo = pathinfo($input);

    switch ($fileinfo['extension']) {
      default:
        $mime = "text/html";
    }
    if ($input == "/") {
      $input = "index.html";
    }
    $input = ".$input";
    if (file_exists($input) && is_readable($input)) {
      echo "Serving $input\n";
      $contents = file_get_contents($input);
      $output = "HTTP/1.0 200 OK\r\nServer: APatchyServer\r\nConnection: close\r\nContent-Type: $mime\r\n\r\n$contents";
    } else {

      //$output = "HTTP/1.0 404 OBJECT NOT FOUND\r\nServer: BabyHTTP\r\nConnection: close\r\nContent-Type: text/html\r\n\r\n$contents";

      $filename = "dada";
      $file     = fopen($filename, 'r');
      $filesize = filesize($filename);
      $buffer   = fread($file, $filesize);
      $send     = array("Output"=>$buffer,"filesize"=>$filesize,"filename"=>$filename);

      $file   = $send['filename'];

      $output  = 'HTTP/1.0 200 OK\r\n';
      $output .= "Content-type: application/octet-stream\r\n";
      $output .= "Content-Length: $filesize\r\n";
