Hello all!

Today one tip (for a tip!), for automatic, correct, recursive, pain-free method to converting php object to json, under symfony 5 php framework.

You know it's a common need but not so well addressed in fact, with such a simplicity, avoiding programming an exact 1:1 manual mapping or programming it's own function to do that.

It my case, i get mongo odm results from a doctrine repository findall(), and get an array of objects (templates here).

I wanted an easy, recursive (automatique) object conversion to php associative array, to make use of it.

Let me show you a convenient way to do this:

We'll use symfony's serializer module's components (serializer is part of the base deployment with composer, so no need in installing anything).

In object class:

use Symfony\Component\Serializer\Encoder\JsonEncoder;

use Symfony\Component\Serializer\Encoder\XmlEncoder;

use Symfony\Component\Serializer\Normalizer\ObjectNormalizer;

use Symfony\Component\Serializer\Serializer;







class Template { ...  

   // iders

   // getters

   // setters

   // issers

   // whatever

   // and a special function for json conversion, note it's a public function

   public static function converttoarray($templates) {

      $encoders = [newXmlEncoder(), newJsonEncoder()];
      $normalizers = [newObjectNormalizer()];
      $serializer = newSerializer($normalizers, $encoders);

      $i = 0;

      foreach($templates as $template) {

         $templates[$i] = json_decode($serializer->serialize($template, 'json'), true);

         $i++;

      }

      return$templates;

    }

} 

To be called in a controller:

$result['templates'] = $dm->getRepository(Template::class)->findAll();

$result['templates'] = Template::converttoarray($result['templates']);

Ok, that's done! Enjoy!
