Dynamically generate classes at runtime in php?

Question

Here\'s what I want to do:

$clsName = substr(md5(rand()),0,10); //generate a random name
$cls = new $clsName(); //create a new instance

function __autoload(         


        

Answer 1

We can create class instance dynamically by following way

I also face this issue in Laravel 5.8 version and now it is working fine for me.

Give full path instead of the class Name

class TestController extends Controller
{
    protected $className;

    public function __construct()
    {
        $this->className = 'User';
    }

    public function makeDynamicInstance()
    {
        $classNameWithPath = 'App\\' . $this->className; 
        $classInstance = new $classNameWithPath;
        $data = $classInstance::select('id','email')->get();
        return $data;
    }
}

Output

Illuminate\Database\Eloquent\Collection Object
(
    [items:protected] => Array
        (
            [0] => App\User Object
                (
                    [fillable:protected] => Array
                        (
