/*
 * This PHP script enables users to receive an invitation to a specified GitHub organization by submitting their GitHub username. 
 * It handles POST requests from a simple form, sanitizes the input username, and uses the GitHub API to send an invitation to 
 * the provided GitHub username to join the organization. The script utilizes cURL for API communication and requires a valid 
 * personal access token with sufficient permissions. It includes basic error handling to provide feedback on the success or failure of the invitation process.
