PHP Sockets in Realtime - php

Question

Background
A desktop application on a user's computer gets the phone number from the modem and sends it to a PHP script once a phone call is recieved. At the moment, I am able to receive the data/packet on the specified port via PHP. I then have a scraper that connects to 411 databases and returns the address for the specified phone number.
Problem
After I retrieve the phone number in PHP through sockets, how can I automatically update the 411 parser page with the new phone number?
Code
socket_listener.php
set_time_limit(0);
$address = "127.0.0.1";
$port = 10629;
// create socket and bind with listener event
$socket = socket_create(AF_INET, SOCK_STREAM, SOL_TCP);
socket_bind($socket, $address, $port);
socket_listen($socket);
do {
$accept = socket_accept($socket);
$read = socket_read($accept, 1024) or die("Could not read input\n");
// parse phone number
$phone = substr($read, 19, 15);
$file = fopen("phone_numbers.txt", "a");
fwrite($file, $phone . "\r\n");
fclose($file);
} while (true);
phone_numbers.txt
[phone]
[phone]
Current Solution
My current solution is pretty quirky.
modem -> desktop application -> socket_listener.php -> data.txt -> 411_scraper.php
socket_listener.php listens on the port for incoming packets 24/7 and appends new phone numbers it receives to a text file
411_scraper.php checks text file for updates every 5 seconds. If file version is changed, then it reads the last phone number
Run code to query 411.com and retrieve data using phone number
Desired Solution
socket_listener.php listens on port for incoming packet containing phone number
Page automatically updates with new data retrieved from 411
Things I've Been Looking At
I've looked at node.js, Ratchet (www.socketme.com), and Pusher (http://pusher.com/) but they are all above my level of understanding. Pusher and Ratchet seems promising but I have not jumped into them yet.

I would use ajax or something along those lines. PHP isn't a real time thing. When you navigate to a website which uses PHP the code is executed before the page is rendered. It's processing the code on the server computer and giving you back the result as a string which you can send to the requesting client.
You're going to have the hold the data somewhere persistently. Once the php script is done executing the data is for that execution gone. Unless you use sessions.
