How to delete multiple images

Hi all, May you help me with how to delete multiple images with modal.
I do for one file but I want to assign it like this (array) How?

PHP Code:

public function delete($images_id)       
      {
        $data = $this->model->find($images_id);
        
        $imagefile1 = $data['image1'];
        $imagefile2 = $data['image2'];
        $imagefile3 = $data['image3'];
        $imagefile4 = $data['image4'];
        
        if(file_exists("imagedirector/"$imagefile)){

             foreach($imagefile as $delete){
                unlink("imagedirector/".$imagefile ++);
             }            
        }
