Try Rector Online | Rector - Automated Way to Instantly Upgrade and Refactor any PHP code

Run Rector on your code to see what it can do for you:

 {
     public function run(bool $param)
     {
-        $constraints = new Assert\Collection([
-            'distributorCode' => [new Assert\NotBlank(), new Assert\Type('string')],
-            'warehouseId' => [new Assert\Type('string')],
-            'customerCode' => [new Assert\NotBlank(), new Assert\Type('string')],
-            'clientAddressId' => [new Assert\NotBlank(), new Assert\Type('string')],
-        ]);
+        $constraints = new Assert\Collection(distributorCode: [new Assert\NotBlank(), new Assert\Type('string')], warehouseId: [new Assert\Type('string')], customerCode: [new Assert\NotBlank(), new Assert\Type('string')], clientAddressId: [new Assert\NotBlank(), new Assert\Type('string')]);
     }
 }

PHP snippet to change

<?php

use Symfony\Component\Validator\Constraints as Assert;

final class DemoFile
{
    public function run(bool $param)
    {
        $constraints = new Assert\Collection([
            'distributorCode' => [new Assert\NotBlank(), new Assert\Type('string')],
            'warehouseId' => [new Assert\Type('string')],
            'customerCode' => [new Assert\NotBlank(), new Assert\Type('string')],
            'clientAddressId' => [new Assert\NotBlank(), new Assert\Type('string')],
        ]);
    }
}
