2.install php 5.6

sudo apt-get install software-properties-common sudo add-apt-repository ppa:ondrej/php5-5.6 sudo apt-get update sudo apt-get upgrade sudo apt-get install php5 

3. while returning views, use foldername.viewname instead of foldername\viewname

4. use public_path() while including files

5. chmod -r 777 "storage folder path"
