Good afternoon.
I say this all the time, and I'll say it again - I'm not a php specialist at all, but I need to do it)
In the index.php file, simple variables are displayed, such as Company name $company_name, Company phone number &company_phone, and so on, there are many variables.
Some of them are clogged through the admin panel, and some I need to hide for personal use.
So that later it would be convenient to change just in one file.
What file to create (what format)? And how to refer to a specific line of a file?

create a config.php file (the name is not important)
in index.php, where you have html c header footer content body head
insert the following code at the very beginning of the file:

<?php
include 'config.php';
?>
<html>
<head>
  ...

The php config file itself has the following content:

<?php
$my_config = array(
  'company' => 'Hello world',
  'author' => 'Ivan Ivanov'
);

Further in the file where config.php was connected via include.
In the place where you need to display the value from the config:
<?=$my_config['author']; ?>

Under configs, there is one very convenient approach: configs in class constants.
The meaning is as follows, create a basic config, for example, DefaultConfig.php, set the settings for the development environment

namespace MyVendor\MyProject\Config;

class DefaultConfig
{
    const MYSQL_DSN = 'mysql:host=localhost;dbname=dbName';
    const MYSQL_USER = 'some_user';
    const MYSQL_PASS = 'some_password';
}

You also create a config that will be connected in your project Config.php (git/svn/or whatever you have there is ignored)

namespace MyVendor\MyProject\Config;

class Config extends DefaultConfig
{
}

The point is, you can access any settings directly using autoload, while redefining them for production, for example, is very simple - you redefine a constant in Config.php.
Due to this, your connection to the database may look like this:

$pdo = new PDO(
    Config::MYSQL_DSN,
    Config::MYSQL_USER,
    Config::MYSQL_PASS
);
