PHP URL Shortener

This is a simple URL shortener written in PHP. It does not require a database, as the original URL is encoded directly into the shortened URL itself. This project is ideal for lightweight applications where you want to quickly create and share shortened URLs without the overhead of database management.

Features

• No Database Required: URLs are encoded within the URL itself, eliminating the need for database storage.
• Simple Encoding/Decoding: Uses Base64 encoding to shorten URLs.
• Automatic Redirection: Automatically redirects users to the original URL when they visit the shortened link.

How It Works

1. URL Encoding: The original URL is Base64 encoded and made URL-safe by replacing certain characters.
2. URL Decoding: When a shortened URL is accessed, the script decodes the Base64 string to retrieve the original URL.
3. Redirection: The user is automatically redirected to the original URL.

Installation

   git clone https://github.com/yourusername/php-url-shortener.git

   • Ensure the server has PHP installed and configured.

3. Access the Application:

Usage

1. Shorten a URL:

2. Use the Shortened URL:

   • Share it with others or use it in your web applications.

3. Automatic Redirection:

   • When someone visits the shortened URL, they will be automatically redirected to the original URL.

Example
