PHP Product Catalog with Search and Pagination

This is a simple PHP application that demonstrates a product catalog with search functionality and pagination.

Features

1. Product Storage: Products are stored in a PHP array with details like name, description, price, and category.
2. Search Functionality: Users can search for products by name, description, or category using the search bar.
3. Dynamic Results Display: Search results are displayed dynamically based on user input.
4. Pagination: For better user experience, results are paginated (5 items per page).

How It Works

• The application uses a PHP array to store product information.
• When a user submits a search query via GET request, the application filters the products array.
• The filtered results are then paginated using PHP's array functions.
• The front-end uses HTML and CSS for presentation with a responsive grid layout.

Concepts Demonstrated

• Arrays: Product data is stored and manipulated using PHP arrays.
• Forms: A search form is used to capture user input.
• GET Requests: Search parameters are passed via URL query parameters.
• Pagination: Custom pagination implementation to handle large datasets.

How to Run

1. Place the index.php file in your web server directory.
2. Start your web server (Apache, Nginx, etc.).
3. Access the application through your browser (e.g., http://localhost/index.php).

File Structure

• index.php: Main application file containing all functionality.
• README.md: This documentation file.

Implementation Details

Search Functionality

The search feature uses PHP's array_filter() function to filter products based on the search term. The search checks the product name, description, and category using case-insensitive matching.

Pagination

Pagination is implemented by:

1. Calculating the total number of items and pages
2. Determining the current page from the URL parameter
3. Using array_slice() to extract only the items for the current page

Security

The application uses htmlspecialchars() to prevent XSS attacks when displaying user input and search results.

Customization

You can customize the application by:

1. Adding more products to the $products array
2. Modifying the styling in the CSS section
3. Changing the number of items per page by modifying the $itemsPerPage variable
