I would recommend learning steps like this:<p>+ Update your php knowledge to modern standards. (i.e. autoloader)<p>+ Learn just some sass and use bootstrap 3.<p>+ Use something like laravel as a php framework or even smaller like slim<p>+ DONT get confused by the plethora of JS-Frameworks. 
DONT use build tools in the beginning. 
Plain old &lt;script&gt; tags for the start.<p>Start building something nice.<p>sign up on laracast.com ;)
