WP_Rewrite::wp_rewrite_rules()
Retrieves the rewrite rules.
Contents
Description
The difference between this method and WP_Rewrite::rewrite_rules() is that this method stores the rewrite rules in the ‘rewrite_rules’ option and retrieves it. This prevents having to process all of the permalinks to get the rewrite rules in the form of caching.
Return
(string[]) Array of rewrite rules keyed by their regex pattern.
More Information
It returns the array of rewrite rules as in rewrite_rules(), but using $matches[xxx] in the (where xxx is a number) instead of the normal mod_rewrite backreferences, $xxx (where xxx is a number). This is useful when you’re going to be using the rules inside PHP, rather than writing them out to a .htaccess file.
