[wp-hackers] wp-config.php defining value of ABSPATH

[Utkarsh Dixit]

Hi,

I'm just a beginner to wordpress so it might sound a little naive, in
wp-config.php file we have following lines of code just before including
'wp-settings.php'

if ( !defined('ABSPATH') )
define('ABSPATH', dirname(__FILE__) . '/');


Seems useless to me as we already define ABSPATH in wp-blog-header.php and
suppose if we directly open our wp-config.php file then also if it is a
level above the wordpress root directory the ABSPATH is set to the
directory a level above the wordpress root directory which gives a fatal
error when we include the wp-settings.php file in the next step.Can't we do
it like this?

if ( !defined('ABSPATH') )
define('ABSPATH', dirname(__FILE__) . '/');

if(file_exists(ABSPATH . 'wp-settings.php'))
         require_once(ABSPATH . 'wp-settings.php');


It helps in removing the Fatal error which might occur.
