Can't assign requested address when trying to connect to socket php - php

Question

All this code is run on my local machine
Hi.
I am trying to learn how to properly use sockets.
I created two scripts, the following:
socket.php :
<?php
$address = "10.0.1.13";
$port = 19132;
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
if($socket === false){
console("Failed to create socket.");
exit(1);
}
if(socket_bind($socket, $address, $port) === false){
console("CANNOT BIND SOCKET -BYE!");
exit(1);
}
$stop = false;
$start = microtime(true);
console("Socket started ($address) : $port");
while(!$stop){
}
socket_close($socket);
console("Script stopped.");
function console($message){
echo $message . "\n";
}
?>
reader.php :
<?php
$address = "10.0.1.13";
$port = 19132;
/* Allow the script to hang around waiting for connections. */
set_time_limit(0);
/* Turn on implicit output flushing so we see what we're getting
* as it comes in. */
ob_implicit_flush();
if (($socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP)) === false) {
echo "socket_create() failed: reason: " . socket_strerror(socket_last_error()) . "\n";
}
if(socket_connect($socket, $address, $portph) === false){
console("CANNOT CONNECT SOCKET -BYE!");
exit(1);
}
//socket_set_nonblock($socket);
console("success!");
function console($message){
echo $message . "\n";
}
?>
The goal is too run socket.php, and have reader.php connect to the socket. Though, I am always getting Can't assign requested address when trying to connect to socket with reader.php. I don't understand what am I doing wrong.
How can I fix this?

As per PHP.net
Note:
This function must be used on the socket before socket_connect().
you can refer to - [http://php.net/manual/en/function.socket-bind.php][1]
