How to know whenever the connection is reset by peer in php?

I don't think it's possible the stream_socket family, it looks like it's too high level.

I tried making a very hackish solution, I don't know if it will work for you, it's not very reliable:

<?phpset_error_handler('my_error_handler');function my_error_handler($no,$str,$file,$line) {    throw new ErrorException($str,$no,0,$file,$line);}$socket = stream_socket_server("tcp://0.0.0.0:8000", $errno, $errstr);if (!$socket) {  echo "$errstr ($errno)\n";} else {  while ($conn = stream_socket_accept($socket)) {    foreach (str_split('The local time is ' . date('n/j/Y g:i a') . "\n") as $char) {      echo $char;      try {            fwrite($conn,$char);      } catch (ErrorException $e) {            if (preg_match("/^fwrite\(\): send of 1 bytes failed with errno=([0-9]+) ([A-Za-z \/]+)$/",$e->getMessage(), $matches)) {                    list($errno,$errstr) = array((int) $matches[1], $matches[2]);                    if ($errno === 32) {                            echo "\n[ERROR] $errstr"; // Broken pipe                    }            }            echo "\n[ERROR] Couldn't write more on $conn";            break;      }      fflush($conn);    }    fclose($conn);  }  fclose($socket);}echo "\n";?>

Launch: php ./server.php

Connect: nc localhost 8000 | head -c1

Server output:

The loca[ERROR] Broken pipe[ERROR] Couldn't write more on Resource id #6
