localhost/codeigniter shows index.php instead of welcome_message.php - php

Question

Hi I'm fairly new to server configurations, apache and codeigniter. I installed apache on my ubuntu 16.04, created a html file(index.html) in DocumentRoot of my server (that is var/www/html) just to check if it works. When I enter "localhost" to url bar in firefox it shows the index.html file(So I assume it works?). But when I tried to install codeigniter(by copying all downloaded codeigniter files to a new directory(named codeigniter) under DocumentRoot of my server as stated in the guide) and go to localhost/codeigniter instead of the welcome_message this shows on the page:
=')) { error_reporting(E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_STRICT & ~E_USER_NOTICE & ~E_USER_DEPRECATED); } else { error_reporting(E_ALL & ~E_NOTICE & ~E_STRICT & ~E_USER_NOTICE); } break; default: header('HTTP/1.1 503 Service Unavailable.', TRUE, 503); echo 'The application environment is not set correctly.'; exit(1); // EXIT_ERROR } /* *--------------------------------------------------------------- * SYSTEM DIRECTORY NAME *--------------------------------------------------------------- * * This variable must contain the name of your "system" directory. * Set the path if it is not in the same directory as this file. */ $system_path = 'system'; /* *--------------------------------------------------------------- * APPLICATION DIRECTORY NAME *--------------------------------------------------------------- * * If you want this front controller to use a different "application" * directory than the default one you can set its name here.

While playing around codeigniter files I noticed that what is shown on the page is directly the content of the file var/www/html/codeigniter/index.php
after the 78th line. I don't think I changed contents of any file so I have no idea why am I seeing this instead of the welcome_message.
I also tried to create another view to see if the problem was about welcome_message by creating the necessary php files
under controller and views directories and when I try to go localhost/codeigniter/newview I get 404 not found error.
I would be glad if you could help. Thanks in advance.

Answer 1

in Application/Config/Config.php
in thatYou can Set Any default view file
$config['index_page'] = ''; or $config['index_page'] = 'welcome_message.php';
Or
You can set Default controller in application/config/routes.php
$route['default_controller'] = 'CONTROLLER Name/METHOD Name(optional)';
if you set that default controller it will load that method and view file in that method. so you can set controller and method name to view page which you want.
