Best Practices for PHP

Baseline

Follow the Wordpress PHP Coding Standards

• Use tabs instead of spaces

• Use { } even when they're not necessary:

  if ( condition ) { action0(); }

• Remove trailing spaces

One notable exception to WordPress' rules is that we do not use spaces or tabs for indentation within a line of code.

Other things:

• When something goes wrong, use an Exception.
• Use namespaces.

Documentation

INN's PHP projects use phpDocumentor-style documentation comments, following the WordPress standard.
