A solid tutorial covering what functions are available to you when building patterns. For example, did you know that patterns are executed on init, a time when most WP conditionals are not yet set?

Why use PHP? Internationalization, dynamic URLs for loading media, and more.

You can also do things like loops instead of printing the block markup for repeated sections of the pattern with the same content (for example, a Columns block with the same nested columns).
