stream_set_timeout & stream_get_meta_data

[kali707]

hi guys,

 

Just created my id on this forum. posting for the first time. The socket server does not send an EOF. Instead it sends a code to signal the end of the data. In the following code socket is opened without any problems. fputs works fine. But when the while loop is executed $info['timed_out'] is FALSE for each iteration as long as $info['unread_bytes'] != 0. In the last iteration $info['timed_out'] becomes TRUE (dont' know why). So, in the last iteration data does not get appeneded to $resp_all.

 

What I am trying to do is to make sure that I have read all the data through the socket until that end-of-data signal/code is received (there is no EOF sent by the server). So I am trying to make sure that the data is not half-read or incomplete. If there is a timeout reading the data it should try again (at least 3 times). If you have any other suggestions/ideas to accomplish this please let me know.

 

   $fp = fsockopen($host, $port, $errno, $errdesc, 5);
   fputs($fp, $msg);

   $tryCnt = 1;
   stream_set_timeout($fp, 35);
    
   while ($tryCnt <= 3) 
   {
      $rsp = fgets($fp, 1024);
      $info = stream_get_meta_data($fp);
      if ($info['timed_out']) {
       $tryCnt += 1;
       continue;
      } 
      $rsp_all .= $rsp;
     # check for end of data signal and if there is, then break out 
   }
