Functions such as array_map(), array_filter(), and array_reduce() are among the most versatile tools in any PHP developer’s toolkit. Used well, they replace verbose loops with expressive, readable pipelines that communicate intent at a glance.
How It Works
Understanding your audience is the foundation of effective communication. Before writing a single word, ask yourself: who is this for, and what do they need to walk away knowing? Every decision — tone, structure, vocabulary — should flow from the answer to that question.
- Plan your project structure before writing a single line of code
- Write tests early and run them often throughout development
- Document your decisions as well as your implementations
- Review your own code as if a colleague wrote it
