How to make this socket server work in PHP?

I am creating a server with PHP sockets, I have created the server file.php and I have uploaded it to my VPS. I created a client.php to test and I open it from localhost, the case is that it always tells me that it is impossible to connect to the server via port 10000.

These are the codes (they are very simple to test).

Server.php

#!/usr/local/bin/php -q
<?php
$socket = socket_create(AF_INET,SOCK_STREAM,SOL_TCP);
socket_bind($socket,'127.0.0.1',10000);
socket_listen($socket);

echo "Esperando conexión\n\n";
$conn = false;
switch(@socket_select($r = array($socket), $w = array($socket), $e = array($socket), 60)) {
case 2:
echo "Conexión rechazada!\n\n";
break;
case 1:
echo "Conexión aceptada!\n\n";
$conn = @socket_accept($socket);
break;
case 0:
echo "Tiempo de espera excedido!\n\n";
break;
}
if ($conn !== false) {
  socket_write($conn, "TE HAS CONECTADO PERFECTAMENTE", srtlen("TE HAS CONECTADO PERFECTAMENTE"));
}
?>

Client.php

<?php
$host = "IP DE MI VPS";

$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
$puerto = 10000;

if (socket_connect($socket, $host, $puerto))
{
echo "\nConexion Exitosa, puerto: " . $puerto;
$out = socket_read($socket, 2048);
echo $out;
}
else
{
echo "\nLa conexion TCP no se pudo realizar, puerto: ".$puerto;
}
socket_close($socket);
?>

To leave the server open as a daemon in linux I use the command:

nohup php servidor.php > errores.log &

I don't know why it doesn't make the connection, I guess it will open to open the port or something. It's the first time I've tried to do something like this.
