How This System Works — Code Explained
Most students download, run, and move on. But if you understand how the code actually works, you can modify it, extend it, and explain it confidently in your viva or job interview. Here is a breakdown of the most important parts.
The Database Structure
The system runs on 6 core tables. Understanding their relationships is the foundation of understanding the whole project:
- customers — name, contact, address, and the plan they are subscribed to
- internet_plans — plan name, bandwidth speed, and monthly price
- bills — generated monthly per customer, stores amount, due date, and payment status
- collections — actual payments recorded against bills
- expenses — ISP operational cost records
- stock — hardware inventory (routers, modems, cables, switches)
The key relationship is Many-to-One between customers and internet_plans — many customers share one plan, but each customer has only one active plan at a time. The bills table locks in both customer_id and plan_id at billing time, so even if a customer upgrades later, old bills always reflect the original price charged. This is called denormalization for historical accuracy — worth mentioning in any viva.
customers.plan_id → internet_plans.id
bills.customer_id → customers.id
bills.plan_id → internet_plans.id (price locked at billing time)
collections.bill_id → bills.idSession-Based Authentication
Every page starts with this check. If no active admin session exists, the visitor is immediately redirected to the login page:
<?php
session_start();
if (!isset($_SESSION['admin_id'])) {
header("Location: login.php");
exit();
}
?>Database Connection
Configured once in config/dbconnection.php and included on every page that needs database access. When deploying to a live server, this is the only file you need to update:
<?php
$host = "localhost";
$dbname = "isp_db";
$username = "root";
$password = "";
$conn = mysqli_connect($host, $username, $password, $dbname);
if (!$conn) {
die("Connection failed: " . mysqli_connect_error());
}
?>How Monthly Billing Works
When the admin clicks “Generate Bills,” a PHP script runs this logic: fetch all active customers with their plan price, check whether a bill already exists for this month, and insert a new one only if it does not. The duplicate check is what prevents double-billing if the button is clicked twice — a small detail that shows professional thinking:
<?php
$query = "SELECT c.id AS customer_id, c.name, p.id AS plan_id, p.price
FROM customers c
JOIN internet_plans p ON c.plan_id = p.id
WHERE c.status = 'active'";
$result = mysqli_query($conn, $query);
$month = date('Y-m');
$due_date = date('Y-m-28');
while ($row = mysqli_fetch_assoc($result)) {
// Prevent duplicate bills for the same month
$check = "SELECT id FROM bills
WHERE customer_id = {$row['customer_id']}
AND DATE_FORMAT(created_at, '%Y-%m') = '$month'";
$exists = mysqli_query($conn, $check);
if (mysqli_num_rows($exists) == 0) {
$insert = "INSERT INTO bills (customer_id, plan_id, amount, due_date, status)
VALUES ({$row['customer_id']}, {$row['plan_id']},
{$row['price']}, '$due_date', 'unpaid')";
mysqli_query($conn, $insert);
}
}
?>Dashboard Summary Queries
The four numbers on the dashboard are each generated by a simple MySQL aggregate query:
<?php
$total_customers = mysqli_fetch_row(
mysqli_query($conn, "SELECT COUNT(*) FROM customers WHERE status='active'")
)[0];
$pending_amount = mysqli_fetch_row(
mysqli_query($conn, "SELECT SUM(amount) FROM bills WHERE status='unpaid'")
)[0];
$monthly_expenses = mysqli_fetch_row(
mysqli_query($conn, "SELECT SUM(amount) FROM expenses
WHERE MONTH(date) = MONTH(NOW())
AND YEAR(date) = YEAR(NOW())")
)[0];
$total_plans = mysqli_fetch_row(
mysqli_query($conn, "SELECT COUNT(*) FROM internet_plans")
)[0];
?>How to Extend This Project
Adding even one of these extensions will immediately set your submission apart from everyone else who downloaded the same files. Each one is practical and achievable for an intermediate PHP student.
01 Automate Billing with a Cron Job
Instead of the admin manually clicking “Generate Bills” each month, schedule a cron job to run automatically on the 1st of every month. On a Linux server: 0 9 1 * * php /path/to/generate_bills.php. This single change transforms the project from a manual tool into a fully automated billing system.
02 Send Email Notifications with PHPMailer
After each bill is generated, automatically email the customer with their invoice details — plan name, amount, and due date. PHPMailer is free, installs via Composer, and takes about 30 lines of code to set up. It makes the system feel like a real commercial product.
03 Add an AI Customer Support Chatbot
Integrate a simple OpenAI-powered chatbot on the customer-facing side that answers questions like “What is my current plan?” or “When is my bill due?” Requires about 20 lines of JavaScript and a free API key. In 2026, this kind of AI integration is exactly what examiners and employers want to see.
04 Build a Customer Self-Service Portal
Add a separate customer login where subscribers can view their own bills, check payment history, and see their current plan — without needing to contact the admin. Requires a customer session table and role-based access control.
05 SMS Alerts via Twilio
Use the Twilio API (free trial available) to send customers an SMS when a bill is generated or overdue. In many markets, SMS is far more reliable than email for billing notifications. Practical, real-world, and impressive to demo.
06 Revenue and Analytics Dashboard
Add a reporting page showing monthly revenue trends, most popular plans, top paying customers, and expense breakdowns using Chart.js. All data is already in your database — you just need GROUP BY queries and a JavaScript chart to visualize it. Charts always impress in presentations.
Deploying to a Live Server
Once tested locally, deploying to shared hosting (Hostinger, Namecheap, or any cPanel host) takes about 10 minutes:
Step 1 – Upload Your Files
Log in to cPanel, open File Manager, navigate to public_html, and upload your project folder. Or use FileZilla FTP for larger transfers.
Step 2 – Create a MySQL Database
In cPanel go to MySQL Databases. Create a new database, create a user, assign the user full privileges on that database, and note down the credentials.
Step 3 – Import the SQL File
Open phpMyAdmin from cPanel, select your new database, click Import, and upload the kp_db.sql file. All tables and data are created automatically.
Step 4 – Update Config
<?php
$host = "localhost"; // Usually still localhost on shared hosting
$dbname = "youraccount_isp_db"; // Your hosting database name
$username = "youraccount_user"; // Your hosting DB username
$password = "your_password";
?>Step 5 – Visit Your Live URL
Go to https://yourdomain.com/isp-management-system/ and log in. Your system is now live on the internet.
💡 Recommended hosting: Hostinger’s basic shared plan supports PHP 8, MySQL, and cPanel for around $2–3/month — one of the most affordable options for deploying student PHP projects to a real URL.
Common Errors and Fixes
| Error | Cause | Fix |
|---|---|---|
Access denied for user 'root' | Wrong DB credentials in config file | Open config/dbconnection.php and check database name, username, and password. On fresh XAMPP the password is empty "". |
Table doesn't exist | SQL file was not imported | Open phpMyAdmin, select your database, and import kp_db.sql. Verify the tables appear in the left sidebar. |
| Blank white page, no error | PHP errors are suppressed | In php.ini set display_errors = On and restart Apache. The real error message will then appear. |
| 404 Not Found | Folder name mismatch | Make sure the folder inside htdocs is named exactly isp-management-system and the URL matches. |
| Login fails with correct password | Password stored as MD5 hash | Open phpMyAdmin, find the admin record, check the password field. If hashed, generate the MD5 of your new password and paste it directly. |
Frequently Asked Questions
How do I add a new internet plan?
Log in as admin and go to the Internet Plans module in the sidebar. Click “Add New Plan,” enter the plan name, bandwidth speed, and monthly price. The plan is immediately available to assign to any customer.
Can I deploy this on shared hosting like Hostinger or Namecheap?
Yes. Upload the files via FTP or File Manager, create a MySQL database from cPanel, import kp_db.sql, and update config/dbconnection.php with your hosting credentials. Everything else works exactly as on localhost.
How do I reset the admin password?
Open phpMyAdmin, find the admin table, and edit the password field directly. If the value is an MD5 hash, use an online MD5 generator to create the hash of your new password before saving.
Can I add multiple admin users?
The default version supports one admin. To add multi-user support, create a users table with a role column (admin, billing staff, support) and check $_SESSION['role'] on each restricted page.
How do I change the currency symbol in bills?
Use VS Code’s Find and Replace across all PHP files to swap the hardcoded currency symbol to your local one (e.g. PKR, INR, NGN, USD).
Is this suitable for a final year submission?
Yes — it covers authentication, CRUD operations, relational database design, billing logic, and inventory in one application. Strengthen it by adding one extension, preparing an ER diagram, writing an SRS document, and practicing your explanation of the billing module for the viva.
Can I connect this to a mobile app?
Not directly, but you can convert the core modules into a PHP REST API that returns JSON. A React Native or Flutter app can then connect to that API. This makes for an impressive advanced extension.
What PHP version does this need?
PHP 5.6 and above works, but PHP 7.4 or PHP 8.x is recommended. XAMPP’s latest versions ship with PHP 8 by default so most students will not need to change anything.
Is this safe to use for a real ISP business?
With modifications, yes. For a live production environment you should switch to PDO with prepared statements (to prevent SQL injection), add HTTPS, use password_hash() for passwords, and validate all form inputs. As a learning project it is excellent; as a commercial deployment those security improvements are essential.
What You Learn by Studying This Project
Relational Database Design
The system uses foreign keys, JOIN queries, and aggregate functions in a real business context. Understanding how bills connects to both customers and internet_plans teaches you the same patterns used in e-commerce platforms, banking systems, and SaaS applications.
Session Management and Security
The session-based authentication pattern here is the foundation of PHP web application security. Understanding how $_SESSION works, why session_start() must appear on every page, and how to protect routes from unauthorized access are skills every PHP developer needs.
MVC-Like Code Organization
The project separates configuration, business logic, and presentation into distinct files. While not a strict framework, this structure mirrors how Laravel and CodeIgniter organize code — making it much easier to pick up a framework after studying this project.
CRUD in a Business Context
Adding a customer, generating a bill, and recording a payment are all CRUD operations — but done in a way that has real business meaning. This is far more valuable to learn from than isolated textbook exercises.
