How to add data when loading CI4 library

Hi Team,
I have had to bite the upgrade bullet. Generally I find the docs excellent, but I have hit a small issue with upgrading a CI3 load->library call which includes an array of parameters
ie
            //Load library
            $config['upload_path'] = $upload_folder;
            $config['allowed_types'] = 'jpeg|jpg|png';
            $config['max_size'] = $max_size * 1024;
            $config['file_name'] = $col.'_'.$row; //Temp name
       
            $this->load->library('upload', $config);
            $this->load->library('image_lib');
I can find no help on this migration.
Can anyone point me in the right direction please or explain what I need to refactor perhaps?
TIA, Paul

Terse! My question was nothing to do with file uploads.

What is the meaning of three dots (...) in PHP?

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

Sorry, I guess I misunderstood your question.
So you have your own library and want to rewrite it to work with CI4?

In that case, instead of

PHP Code:

$this->load->library('whatever', $config); 


you will do

PHP Code:

$whatever = new \App\Libraries\Whatever($config); 


Alternatively, you can also use service to get a single instance every time: https://codeigniter.com/user_guide/conce...vices.html

If that again not what you're asking for, I'm afraid you have to explain the question better.

Thx, just what I wanted. I suppose the "..." comment was a pointer to unpacking associative arrays (new in php8). From what I have read the keys have to be defined in the constructor for the unpacking to work. (Just in case someone reads this thread in the future!)
