ROUTE AND CONTROLLER (ref: https:\/\/knpuniversity.com\/screencast\/symfony\/route-controller#play)
\nModify \/config\/routes.yaml FILE TO UNCOMMENT THE CONTENT AND CHANGE THE CONTROLLER AND THE ACTION:<\/p>\n
index:\r\n    path: \/\r\n    controller: App\\Controller\\ArticleController::homepage\r\n<\/pre>\n
CREATE THE CONTROLLER ‘ArticleController’\u00a0 FILE AND CLASS. ALSO CREATE ‘homepage’ FUNCTION IN\u00a0\/src\/Controller\/ArticleController.php:<\/p>\n

REFRESH THE BROWSER: http:\/\/symfony4test.test\/
\nIT’D SHOW ‘Hello, This is my first page!’ TEXT!<\/p>\n
USE ANNOTATION ROUTE (PREFERRED) INSTEAD OF MODIFYING \/config\/routes.yaml

# Use the front controller as index file. It serves as a fallback solution when\r\n# every other rewrite\/redirect fails (e.g. in an aliased environment without\r\n# mod_rewrite).

It will\r\n    # work in environments without path prefix as well, providing a safe, one-size\r\n    # fits all solution.
