$client->setAppPath() not worked in PHP SDK

I have set my application root path
$client->setAppPath($path) but the problem is , I am also getting error events from other paths.
example my root folder is
/opt/lampp/htdocs/wordpress/wp-content/plugins/myplugins this is my path. but i am also getting events from other path ie
/opt/lampp/htdocs/wordpres/wp-content/plugins/otherplugins

This was resolved/closed on the issue tracker, as it was simply confusion in what the feature does.
