1. Consistent Formatting

• Use consistent indentation (e.g., 2 or 4 spaces) throughout your code.
• Maintain consistent naming conventions (camelCase, snake_case, etc.) for variables and functions.

2. Remove Unused Code

• Eliminate any commented-out code or unused functions and variables. This reduces clutter and confusion.
• Use tools like linters to identify unused variables or functions.

3. Organize Functions

• Group related functions together.
• Consider separating functions into different files or classes based on functionality (e.g., utility functions, API calls).

4. Add Comments and Documentation

• Write clear comments that explain the purpose of complex code blocks.
• Consider using PHPDoc or similar documentation styles to describe your functions, parameters, and return values.

5. Refactor Complex Logic

• Break down large functions into smaller, reusable functions that do one thing.
• Use meaningful names for functions and variables to clarify their purpose.

6. Use Version Control

• Utilize version control systems like Git to track changes and manage your codebase.
• Commit regularly with clear messages describing the changes made.

7. Adhere to Coding Standards

• Follow established coding standards for the language or framework you are using (e.g., PSR standards for PHP).
• Consider using automated tools (like PHP CodeSniffer) to enforce these standards.

8. Optimize for Performance

• Look for opportunities to optimize your code (e.g., reduce unnecessary database calls, avoid duplicate computations).
• Use caching where appropriate to enhance performance.
