What are the best practices for using associative arrays?

When using associative arrays, it's important to use meaningful keys, avoid deep nesting, and ensure efficient lookups.

Can you give me an example of a meaningful key?

Sure! Instead of using numeric indices, use descriptive keys like 'userName' or 'orderTotal' to make your code more readable.

How can I avoid deep nesting?

To avoid deep nesting, try to flatten your data structure when possible, or use separate associative arrays for related data.

What are some common mistakes to avoid?

Common mistakes include using non-unique keys, not validating input data, and overcomplicating the structure.
