Composer

Hello!
Found the code on hithub
0. downloaded (insta desktop)

The instruction contains this:
require __DIR__.'/../vendor/autoload.php';
$ig = new \InstagramAPI\Instagram();
where to prescribe it - did not understand.
Please tell me how to work with this?

Answer 1

The composer works simply: it aggregates all files with all classes and includes them into 1 file, which you must include for yourself. Further, all classes, methods, variables, etc. from installed libraries become available to you in your script after you include autoload.php .
autoload.php - this is the file where the composer connects the rest of the scripts. It lies in the vendor folder next to the installed composer.
So write:

require_one __DIR__.'/vendor/autoload.php';
$ig = new \InstagramAPI\Instagram(); //переменной можно пользоваться

This is if you have a script in the same folder as the composer.

Answer 2

In your script
