• Development Debugging: In a collaborative development environment, it's important to keep track of configuration file updates to avoid inconsistent environments.

The php_ini_loaded_file() function not only helps us quickly locate the actual PHP configuration file being used, but also allows us to monitor file modifications when combined with functions like filemtime(). This method is simple, efficient, and suitable for most environments, enhancing the security and maintainability of PHP projects.
