WordPress Development Stack Exchange is a question and answer site for WordPress developers and administrators. It's 100% free, no registration required.

It's common for plugin developers to protect their plugins from direct access. I saw two ways to do that:

if ( ! defined( 'WPINC' ) ) die;

and

if ( ! defined( 'ABSPATH' ) ) exit;

What are the differences between WPINC and ABSPATH? Which one is the 'right' way to do it?

They are defined as follows:

define( 'ABSPATH', dirname(dirname(__FILE__)) . '/' );
define( 'WPINC', 'wp-includes' );

dirname is a PHP function that returns the path of the parent directory, and wp-includes is pretty self explanatory.

I would say ABSPATH is better because it's one of the first things WP loads and it also looks better:) But there is no real "right way" because they both work.

There is no real right way, and I always use if ( ! defined( 'ABSPATH' ) ) exit;... but, maybe, consider that the scope of this snippet is ensure that wordpress is loaded 'WPINC' is better because is more wordpressfull staring with 'WP'. –  G. M. Jul 31 '13 at 4:53
