Can you help me translate this code and find the php that I need to modify?

Hello - I am trying to modify the PHP code on a site so that I can adjust the title bar.  Yet I am not sure which php file I need to modify!

When I go to index.php (in the public_html folder) I get the following.  What exactly does this mean, and is this trying to point me in the direction of the real php code that powers the site?

<?php

	error_reporting(E_ALL);
	$system_folder = "qmax";
	$application_folder = "application";
	$public_folder = "public_html/";

$modules_folder = realpath(dirname(__FILE__)).'/'.$system_folder.'/'.$application_folder.'/modules/';
$assets_folder = realpath(dirname(__FILE__)).'/assets';
$templates_folder = realpath(dirname(__FILE__)).'/assets/templates';
$public_folder = realpath(dirname(__FILE__));
	
if (strpos($system_folder, '/') === FALSE)
{
	if (function_exists('realpath') AND @realpath(dirname(__FILE__)) !== FALSE)
	{
		$system_folder = realpath(dirname(__FILE__)).'/'.$system_folder;
	}
}
else
{
	$system_folder = str_replace("\\", "/", $system_folder); 
}

define('EXT', '.'.pathinfo(__FILE__, PATHINFO_EXTENSION));
define('FCPATH', __FILE__);
define('SELF', pathinfo(__FILE__, PATHINFO_BASENAME));
define('BASEPATH', $system_folder.'/');
define('ASSETSPATH', $assets_folder.'/');
define('TEMPLATESPATH', $templates_folder.'/');
define('PUBLICPATH', $public_folder);
define('CACHEPATH', $system_folder.'/cache/');

if (is_dir($application_folder))
{
	define('APPPATH', $application_folder.'/');
}
else
{
	if ($application_folder == '')
	{
		$application_folder = 'application';
	}

	define('APPPATH', BASEPATH.$application_folder.'/');
}
define('MODPATH', $modules_folder);

require_once BASEPATH.'main/Main'.EXT;

I would try the /assets/templates folder first and see if there is a header template in it. If not, one of the templates in that folder might shed some more light on where to look.

Based on the code I guess it's using Codeigniter framework.  To get the actual default page, please follow the steps:
1. look into the folder public_html/application/config
(If there's no such folder then I'm guess it wrong about using "Codeigniter".  Just ignore me.)
2. there should be a file called "routes.php"
3. in the php file look for a line that starts with $route['default_controller'], and remember the value of it
4. go into public_html/application/controllers folder
5. there should be a php file whose filename is the value from point 3

That's the file you should be looking at.

Are you telling us that when you go to index.php, it exposes PHP source code instead of rendering an HTML document?
