How to upload Symfony project to shared hosting (bluehost https://goo.gl/gZQEDB)
Create a folder outside the public folder (name folder whatever you want in my case I named it dot)
upload file to that folder (dot folder)
check the public html folder if there is .htacess and if it has then remove it
move the files in "web" folder to public html or public directory
change the configuration by going to the app/config folder and find file name parameters.yml and edit it ( change database name, username, password)
find the file app.php in the "pubic html" folder and correct the path of
autoload.php and bootstrap.php.cache
now delete folder "prod" in the var/cache directory (it would be better if you delete that folder before upload file to share hosting)
