Retrieves the rewrite rules.

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

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.

Source

public function wp_rewrite_rules() {
	$this->rules = get_option( 'rewrite_rules' );
	if ( empty( $this->rules ) ) {
		$this->refresh_rewrite_rules();
	}

	return $this->rules;
}
