Structuring Your PHP Files

Organized code is happy code! PHP file structure in WordPress must mirror certain standards:

• File Naming: Use lowercase letters and separate words with hyphens. For instance, my-custom-plugin.php instead of MyCustomPlugin.php.
• Header Comments: Each file should start with a well-documented header block, providing a quick overview of the file. It should look like this:

  /* Plugin Name: My Custom Plugin Description: Adds custom functionality to my site. Version: 1.0 Author: Your Name */

Consistent structure keeps the project maintainable, allowing team members to pick up where others left off seamlessly.

Coding Style and Best Practices

It’s not just about getting the project done, but doing it cleanly. Adhering to coding styles and best practices signifies professionalism. Here are a few practices you can implement:

• Indentation: Use tabs for indentation, not spaces. This small detail makes a big difference.
• Braces: Open brace { should appear on the same line as the function declaration. Consistency in this small stylistic choice improves readability.
  For example:

  function my_function() { // code here }

• Function Naming: Prefix functions to avoid name conflicts. If you’re working on a plugin, prefix with the plugin name.
• Sanitization: Always sanitize data before publishing it. Trust me, it saves headaches from potential security breaches!

Developing strong coding habits through consistent practices elevates the entire team’s output, making you a more valuable contributor.

PHP’s Functionality and Performance

The performance isn’t all about new functionalities but showing restraint and applying common sense. Optimize your PHP code in WordPress with some simple strategies:

• Use Transients: Cache expensive queries with transients, improving performance by reducing database load.
