Formatting standards cover things like the use of whitespace, how to format control structures, and other aspects that affect your code's appearance and format.

In this tutorial we’ll talk specifically about standards regarding formatting. This is by no means an exhaustive list of PHP syntax rules, but rather is focused on formatting standards for Drupal.

By the end of this tutorial you'll know about the most common Drupal code formatting standards as well as where to find more information when questions arise.

Translations have their own special functions in both Drupal 7 and 8, and there are some rules for standardizing how they are used that make things clearer for everyone.

In this tutorial we'll look at:

• When to use, and when not to use, translation utilities to output translatable strings
• How placeholders work in translatable strings
• Tips for creating links inside of translatable strings

By the end of this tutorial you should know when, and how, to make strings in your code translatable using Drupal's translation utility functions.

Standardized documentation is crucial to a project, whether it is just you or an entire team working on it. In this tutorial we're going to look at:

• Standards for @docblock comments
• Standards for inline comments
• Why standards for documentation and comments are as important as standards for the rest of your code.

By the end of this tutorial you'll know how to add inline documentation for all the PHP code that you write for Drupal.

Once you know what code standards are and why you should use them, you need to learn how to implement Drupal coding standards in your projects. This tutorial will walk through some of the steps you can take to make this as easy as possible. We'll cover:

• Configuring your editor or IDE to warn you of coding standards violations
• Setting up the Coder module and phpcs to scan and review your code
• Performing team code reviews

By the end of this tutorial you should be able to configure your development environment and implement processes in your workflow that help to ensure your code meets Drupal's coding standards guidelines.
