Week 2. Hello World (Includes)
Chapter 2
1. What Are Includes?
- Includes allow you to embed the contents of one PHP file into another.
- They are useful for reusing common elements like headers, footers, or navigation bars across multiple pages.
2. Why Use Includes?
- Consistency: You can maintain a uniform design for your website by centralizing shared components.
- Efficiency: Changes to shared components (e.g., updating a navigation menu) only need to be made once.
- Readability: Code becomes more modular and easier to manage.
- Error Reduction: Centralizing common code reduces the risk of duplication errors.
3. Key Differences Between include and require:
include: Produces a warning if the file cannot be found but continues script execution.require: Produces a fatal error and stops script execution if the file cannot be found.
Note: Using PHP includes effectively promotes clean, efficient, and maintainable code.
