Hello world not working in Zend framework 2

Dear Friends
I am new to Zf2 , installed a skeleton of v 2.2 using composer and to avoid , public folder in URL take the files inside the public folder in to root (index.php, js folder,css folder,fonts folder,img folder) and comment out one line in index.php file
//chdir(dirname(DIR));
So my ZF2 installation in URL : http://localhost/zf2/
