To check if there's a new connection waiting, without blocking, or (when using non-blocking mode) without notices), you can use stream_accept (as opposed to socket_select).

<?php

   
class GenericClass {

        protected
$resSocket=null;

        function
acceptConnections() {

           
# check that we still have a resource
           
           
if(is_resource($this->resSocket)) {
           
               
$arrRead=array($this->resSocket);
               
               
$arrWrite=array();
               
               
/** @warning Passing $arrRead,$arrWrite by reference */
               
if(stream_select($arrRead,$arrWrite,$arrWrite,0)) {
           
                   
$resConnection=stream_socket_accept($this->resSocket,0);

                   
# ... other stuff here
               
}
            }
        }
    }
?>

this function, compared to the function socket_accept, got an extra argument "timeout".
To make this function wait indefinitelly to incoming connections, just as in socket_accept, set timeout to -1. It works for me with PHP 5.0.4.

This code could be very helpfull...

The following code is for the "server". It listen for a message until CTRL-C

<?php
while (true)
{
// disconnected every 5 seconds...
receive_message('127.0.0.1','85',5);
}

function
receive_message($ipServer,$portNumber,$nbSecondsIdle)
{
 
// creating the socket...
 
$socket = stream_socket_server('tcp://'.$ipServer.':'.$portNumber, $errno, $errstr);
  if (!
$socket)
  {
    echo
"$errstr ($errno)<br />\n";
  }
  else
   {
   
// while there is connection, i'll receive it... if I didn't receive a message within $nbSecondsIdle seconds, the following function will stop.
   
while ($conn = @stream_socket_accept($socket,$nbSecondsIdle))
    {
    
$message= fread($conn, 1024);
     echo
'I have received that : '.$message;
    
fputs ($conn, "OK\n");
    
fclose ($conn);
    }
   
fclose($socket);
  }
}
?>

The following code is for the "client". It send a message, and read the respons...

<?php

send_message
('127.0.0.1','85','Message to send...');

function
send_message($ipServer,$portServer,$message)
{
 
$fp = stream_socket_client("tcp://$ipServer:$portServer", $errno, $errstr);
  if (!
$fp)
  {
     echo
"ERREUR : $errno - $errstr<br />\n";
  }
  else
  {
    
fwrite($fp,"$message\n");
    
$response fread($fp, 4);
     if (
$response != "OK\n")
        {echo
'The command couldn\'t be executed...\ncause :'.$response;}
     else
        {echo
'Execution successfull...';}
    
fclose($fp);
  }
}
?>

To whom it may concern, and it may concern you greatly, stream_set_blocking has no effect on stream_socket_accept.
If you want it to return right away, connection or not, use 0 for the timeout parameter.
