The following code, allows only one client and not several at the same time. It is possible to create something, leaves multiple connected clients?
$socket = socket_create( AF_INET , SOCK_STREAM , SOL_TCP );
socket_bind( $socket , 'localhost' , '2000' );
socket_listen( $socket );
while ( true ) {
$client = socket_accept( $socket );
socket_write( $client , 'Aê! Seja bem-vindo!' );
}

Yes, one of the possible ways is with socket_select
http://php.net/manual/en/function.socket-select.php
(recommend using php’s English documentation for socket, as the Portuguese version has almost nothing)
Below an example
...
$clientes = array($socket);
//para o socket_select
$write = null;
$except = null;
while (true)
{
$read = $clientes;
if (socket_select($read, $write, $except, 0) < 1)
continue;
if (in_array($socket, $read))
{
$novo_cliente = socket_accept($socket);
socket_write( $novo_cliente , 'Aê! Seja bem-vindo!' );
//adiciona essa nova conexão ao array $clientes
$clientes[] = $novo_cliente;
}
}

In fact There are several sockets in that code. But is this a real study or application? Because it’s not very common to use sockets in PHP. Nor is it the best language to handle them.
