Description:
------------
The example below is similar to the one posted on the documentation from stream_socket_server on PHP site:

http://php.net/manual/en/function.stream-socket-server.php

I added the "exec" line after the fwrite.  

Before adding the exec line, after the client connects to port 8000, the local time and date is printed, and the client connection is closed.  After adding the exec line, the fclose runs and even returns success, but the client connection doesn't close. The PHP code does continue to execute, so the process is running in the background.  It's not clear to me why the client isn't disconnected after running the fclose.


Test script:
---------------
#!/bin/php72
<?php
$socket = stream_socket_server("tcp://0.0.0.0:8000", $errno, $errstr);
if (!$socket) {
  echo "$errstr ($errno)<br />\n";
} else {
  while ($conn = stream_socket_accept($socket)) {
          fwrite($conn, 'The local time is ' . date('n/j/Y g:i a') . "\n");
          exec("nohup sleep 200 >/dev/null &");
          fclose($conn);
  }
  fclose($socket);
}
?>


Expected result:
----------------
I want the local date and time printed, then the connection to close immediately.

Actual result:
--------------
The date and time is printed, but then the connection hangs.
