stream_socket_accept

(PHP 5)

stream_socket_acceptAcepta una conexión sobre un socket creado por stream_socket_server()

Descripción

resource stream_socket_accept ( resource $server_socket [, float $timeout = ini_get("default_socket_timeout") [, string &$peername ]] )

Acepta una conexión sobre un socket creado previamente por stream_socket_server().

Parámetros

server_socket

El socket del servidor desde donde aceptar una conexión.

timeout

Sobreescribe el tiemo de espera aceptado por defecto del socket. Esto debería darse en segundos.

peername

Se establecerá al nombre (dirección) del cliente que se conectó, si está incluido y disponible desde el transporte seleccionado.

Nota:

También se puede determinar después usando stream_socket_get_name().

Valores devueltos

Devuelve un flujo a la conexión del socket aceptado o FALSE en caso de error.

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.
