I have a plugin that inserts some rewrite rule in the .htaccess file. However, upon deactivating it, doesn't remove said rule. The rule is nested in
# BEGIN My plugin and
# END My plugin.
I want to create an uninstall.php file for this plugin to remove the rule created on acrivation.
I've never done this before. I suppose I can get the .htaccess with
$htaccess = dirname(__FILE__) . '/../../../.htaccess';
should I use a regex or is there a proper way to remove a specific rule from the .htaccess?
