Using a third party library without composer

I would like to use this library in a controller but without installing it with composer. How do i go about that?

Where do I put the library and how do I properly namespace it?

---

Does this look correct?

require APPPATH . 'ThirdParty/HeicToJpg/src/HeicToJpg.php';
use Maestroerror\HeicToJpg;

1) Place the Library in app\ThirdParty

2) Open app\Config\Autoload.php

3) Add the Library to the $classmap

4) 'LibraryName' => APPPATH . 'ThirdParty/Libraryname.php',

5) Top of Controller - Use Libraryname

6) 

PHP Code:

$library = new myLibrary(); 


What did you Try? What did you Get? What did you Expect?

I tried the above, do I need to include anything at the top of my Controller like the use keyword?
If I implement the class like this:


// autoload.php

PHP Code:

public $classmap = [
        'HeicToJpg' => APPPATH . 'ThirdParty/HeicToJpg/src/HeicToJpg.php',
]; 


// Controller in a method

PHP Code:

$fileIsHeic = HeicToJpg::isHeic($_FILES['image-input']['tmp_name']);

if ($fileIsHeic) {
        Maestroerror\HeicToJpg::convert($_FILES['image-input']['tmp_name'])->saveAs($uploads_folder . $filename . '.jpg');
} 


I get the error:
Error: Class "App\Controllers\HeicToJpg" not found

Yes,

You need to add the class with the 'use' keyword.

Try adding:

PHP Code:

use LibraryName
