How to call a class through a router?

Question

Laravel

Here I have a class for loading and resizing images. Yes, the bike is still the same, but I'm just learning.

class Picture
{
    protected $img;
    private $type = array('image/jpeg','image/png');
    public  $size = 300000;

    public function __construct($img)
    {
        $this -> img = $img;
        $this -> checked($img);
        $this -> getSize($img);
        $this -> rename($img);

    }
    protected function checked($img){
        if(in_array($img['type'],$this->type)){
            return $this;
        } else {
            exit('Что это? '. $this->img['type']);
        }
    }
    private function getSize($img)
    {
        if($img['size'] < $this -> size){
            return $this;
        } else {
            exit("Максимальный размер файла:".$this->size);
        }

    }
    private function rename()
    {
        $name = md5(uniqid($this->img['name']));
        $extension = pathinfo($this -> img['name'],PATHINFO_EXTENSION);
        $this-> img['name'] = $name.'.'. $extension;
        return $this;
    }
    public function save()
    {
        move_uploaded_file($this->img['tmp_name'],$_SERVER['DOCUMENT_ROOT']."/image/".$this->img['name']);
        return $this;
    }
    public function resize($new_width)
    {
        list($width, $height) = getimagesize($_SERVER['DOCUMENT_ROOT'].'/image/'.$this -> img['name']);
        $d = $height/$width;
        $new_height = $new_width*$d;
        $base = imagecreatetruecolor($new_width,$new_height);
        if($this->img['type']==='image/jpeg')
        {
            $source = imagecreatefromjpeg($_SERVER['DOCUMENT_ROOT'].'/image/'.$this -> img['name']);
        }
        else
        {
            $source = imagecreatefrompng($_SERVER['DOCUMENT_ROOT'].'/image/'.$this -> img['name']);
        }
        imagecopyresampled($base,$source,0,0,0,0,$new_width,$new_height,$width,$height);
        imagejpeg($base, 'image/small-'.$this->img['name']);
        return $this;
    }
}

I call:

$img = new Picture($_FILES['images']);

$img-> save()
    -> resize(600);

How should it be adapted for Laravel if only 1 method is called in the routing?

Route::get('user/profile', [
    'as' => 'profile', 'uses' => '[email protected]'
]);

After all, I need to run my file in order to change its name, save the original, resize and save a copy, and in 1 method it’s all somehow strange to shove.

Answer 1

I will duplicate what should be called by the controller in the router.
And also I will add from myself:
Laravel has a class for working with files, look at the documentation
laravel.su/docs/5.4/filesystem
And also ONE of the ways to use your class:
1. You must use the namespace App namespace, since Classes are loaded via autoloader.php - composer
2. Create a library folder, in the /app directory, it should look like this: /app/library and fill in the php file with your class
3. For your class, use the namespace App\Library
4. In the controller that handles the route, include your class:
use App\Library\Picture
5. Refer to your class as Picture::staticMethod() or new Picture;
I think you'll figure it out
