ABSPATH or __FILE__?

Question

Can someone tell me if either of these two methods has an advantage over the other and why?

$mydir = ABSPATH.\'/wp-content/themes/mytheme/images\';

Answer 1

ABSPATH is defined variable -> define("ABSPATH",__FILE__); if i directly use magic constant __FILE__ .it will produce same result.

In CMS ABSPATH and framework use BASEPATH is used to get root information in the form of defined variable . In the end with the help of both we get same accurate result.
