title: php socket server disconnecting
body: <p>I'm trying to set up a socket server in php that stays open. This example taken from php.net will close after it receives connection...even after I comment out socket_close($spawn)</p>
  
  <pre><code>&lt;?
  // set some variables
  $host = "192.168.1.109";
  $port = 1234;
  // don't timeout!
  set_time_limit(0);
  // create socket
  $socket = socket_create(AF_INET, SOCK_STREAM, 0) or die("Could not create
  socket\n");
  
  
  // bind socket to port
  $result = socket_bind($socket, $host, $port) or die("Could not bind to
  socket\n");
  // start listening for connections
  $result = socket_listen($socket, 3) or die("Could not set up socket
  listener\n");
  // accept incoming connections
  // spawn another socket to handle communication
  $spawn = socket_accept($socket) or die("Could not accept incoming
  connection\n");
  // read client input
  $input = socket_read($spawn, 1024) or die("Could not read input\n");
  // clean up input string
  $input = trim($input);
  // reverse client input and send back
  //$output = $input . "\n";
  $output = strrev($input) . "\n";
  echo $input;
  socket_write($spawn, $output, strlen ($output)) or die("Could not write
  output\n");
  
  // close sockets
  //socket_close($spawn);
  //socket_close($socket);
  ?&gt;
  
  and here is the code for the client connecting...
  
  &lt;?php
  $fp = fsockopen("192.168.1.109", 1234, $errno, $errstr, 30);
  if (!$fp) {
      echo "$errstr ($errno)&lt;br /&gt;\n";
  } else {
      //$out = "testing";
      $out = "GET / HTTP/1.1\r\n";
      $out .= "Host: 127.0.0.1\r\n";
      $out .= "Connection: Close\r\n\r\n";
      $out .= "testing\n";
      fwrite($fp, $out);
      while (!feof($fp)) {
          echo fgets($fp, 128);
      }
      fclose($fp);
      //exit();
  }
  //exit;
  ?&gt;
