PHP

For PHP projects, we adopt the PSR-2: Coding Standards.

Variables & Properties

The PSR-1 & PSR-2 guides intentionally avoids any recommendation regarding the use of $StudlyCaps, $camelCase, or $under_score for property & variable names. For these, we use the $under_score convention.

Platform/CMS specific

In general, any PHP work on a major platform like wordpess/drupal/etc should adopt, and comply with the standards set by those frameworks.
