What are the best practices for saving and storing PHP scripts?

When saving and storing PHP scripts, it is important to follow best practices to ensure security and maintainability. One common approach is to organize scripts into directories based on their functionality or purpose. Additionally, using version control systems like Git can help track changes and collaborate with other developers. Finally, consider implementing security measures such as input validation and escaping to prevent vulnerabilities.

// Example of organizing PHP scripts into directories

// - /scripts
//   - /auth
//     - login.php
//     - register.php
//   - /utils
//     - validation.php
//     - encryption.php
//   - /views
//     - home.php
//     - profile.php
