Booksmen

Built with PHP

A lightweight library management system demonstrating fundamental PHP concepts for tracking books and member borrowing.

Overview

Booksmen is a single-file PHP application that provides a simple interface for managing a small library catalog. It allows users to view available books, track which member has borrowed each book, and process new borrowings through a straightforward web interface.

How It Works

The application uses two in-memory arrays to store data:

Members Array: Stores library members with their ID and name

['id' => 1, 'name' => 'Alice Johnson']

Books Array: Stores books with title and current borrower (null if available)

['id' => 1, 'title' => 'Harry Potter...', 'borrowed_by' => 1]

Core Functionality

1. Display Books: Shows all books in a table with their availability status
2. Check Status: Displays whether a book is available or borrowed (and by whom)
3. Borrow Books: Processes borrowing via URL parameters (?borrow=1&book_id=X&member_id=Y)
4. Member Lookup: Matches borrower IDs to member names for display

The Borrowing Process

When a user clicks "Borrow as Alice":

1. The URL passes book and member IDs as GET parameters
2. PHP validates the book ID and checks if it's available (borrowed_by === null)
3. If available, the book's borrowed_by field is updated with the member ID
4. The page reloads, showing the updated status

Key PHP Concepts Demonstrated

• Data structures: Associative arrays for entities
• Control flow: if statements and foreach loops
• HTML/PHP integration: Embedding PHP logic in HTML templates
• GET parameters: URL-based state management
• Reference variables: Using &$book to modify array elements
• XSS prevention: htmlspecialchars() for safe output

Installation

1. Clone the repository:

git clone https://github.com/achille010/booksmen.git
cd booksmen

2. Start a PHP development server:

php -S localhost:8000

3. Open your browser to http://localhost:8000

Limitations

• No persistent storage (data resets on page refresh after initial borrow)
• No return functionality
• Hardcoded member options
• No authentication or validation
• Single-user simultaneous access only

This is intentionally minimal to showcase basic PHP web development patterns.

Requirements

• PHP 7.4 or higher
• Web browser
