You, normally, can't call PHP functions in twig directly.

You can however, write a Twig extension

http://symfony.com/doc/current/templating/twig_extension.html

In your case it should look something like this

// src/Twig/AppExtension.php
namespace App\Twig;

use Twig\Extension\AbstractExtension;
use Twig\TwigFilter;

class AppExtension extends AbstractExtension
{
    public function datajalali()
    {
        $articles = "sss";
        $v = new Verta(); //1396-02-02 15:32:08
        $v = Verta::now();

        return $v;
    }

}

With that said, I suppose you could do something like

{{ render(controller(
    'AppBundle\\Controller\\ArticleController ::datajalali'
)) }}

But that seems like bad practice to me, to be honest. I'm not entirely sure it will work properly either.

To be complete, he could also use closures as described in this [post I wrote a while ago](https://stackoverflow.com/questions/34944887/executing-closure-on-twig/47957534#47957534). That being said, I agree, a Twig extension should be the first option to be considered. – Alan T. Feb 07 '18 at 09:28
Thank you.i have error::-> An exception has been thrown during the rendering of a template ("Class "MainBundle\Controller\ArticleController " does not exist."). – pedram shabani Feb 07 '18 at 09:38
Well, there you go, I told you it may not work. I haven't tested it. Go for the extension, seems a lot better. – Andrei Feb 07 '18 at 09:39

Just try to send your datajalali to template, like this:

    return $this->render('MainBundle:Article:index.html.twig', array(
           'lastArticleCategoryData' => $lastArticleCategoryData,
           'datajalali' => $this->datajalali(),
        ));

See How to Embed Controllers in a Template

UPDATE

Andrew and Jonathan Jalouzot told you about twig extensions, but this way is different for symfony3 and symfony4. In your case it looks like this:

class AppExtension extends \Twig_Extension
{
    public function getFunctions()
    {
        return array(new \Twig_Function('datajalali', array($this, 'datajalali')));
    }

    public function datajalali()
    {
        // Your logic here
    }
}

And use it in your template:

{{ datajalali() }}

Hey.thank you for answer.your code work fine but i want to send data to function.i up vote your answer – pedram shabani Feb 07 '18 at 16:00
What's wrong with sending data to function in this case? – Snegirekk Feb 07 '18 at 16:17
i can send parameter in function with this method..for example::: {% datajalali($date) %} – pedram shabani Feb 07 '18 at 16:21
U can do it in your controller `'datajalali' => $this->datajalali( $date )` – Snegirekk Feb 07 '18 at 16:23
In my database, the date of each article is gregorian data.I want to when i print article with for loop.each data print date jalali for this i have class .And then i try convert data at the time of the show. – pedram shabani Feb 07 '18 at 16:35
For example something like this ::-> {% for article in articleIddata %} {{ datajalali( article.creatAt.date) }} {% endfor %} – pedram shabani Feb 07 '18 at 16:38
U can place all your logic in controller. When u get your articles in array u can manipulate them and then send to template. Anyway, my answer was updated with twig extension case for your symfony version. – Snegirekk Feb 07 '18 at 17:36

You need to follow http://symfony.com/doc/current/templating/twig_extension.html

You need to created extension twig.

namespace App\Twig;

use Twig\Extension\AbstractExtension;
use Twig\TwigFilter;
use Verta;

class AppExtension extends AbstractExtension
{
    public function getFunctions()
    {
        return array(
            new TwigFunction('datajalali', array($this, 'datajalali')),
        );
    }

    public function datajalali()
    {
        $articles = "sss";
        $v = new Verta(); //1396-02-02 15:32:08
        $v = Verta::now();

        return $v;
    }
}

You need after add service with tag twig.extension exemple

//service.yml
App\Twig\AppExtension:
    tags: ['twig.extension']

And you can use in your twig template

//twig
{{ datajalali() }}

Hey.thank you for time out.when i use your code i gave this error.:::-----1/1) RuntimeException The definition for "tags" has no class. If you intend to inject this service dynamically at runtime, please mark it as synthetic=true. If this is an abstract definition solely used by child definitions, please add abstract=true, otherwise specify a class to get rid of this error. — pedram shabani, Feb 07 '18 at 16:03
