Are there any best practices for creating custom PHP functions or commands?

When creating custom PHP functions or commands, it is important to follow best practices to ensure readability, reusability, and maintainability of your code. Some best practices include using descriptive function names, following a consistent naming convention, documenting your functions with comments, and keeping your functions small and focused on a single task.
