To use a simple function in Symfony 4, you can follow these steps:

  1. Create a new function in your controller or add it in an existing one. For example, let's create a function that returns the sum of two numbers:
1
2
3
4
public function sum($number1, $number2)
{
    return $number1 + $number2;
}


  1. In the same controller or in another controller, create a new route that will call this function. You can use annotations or the routes.yaml file. For example, using annotations:
 1
 2
 3
 4
 5
 6
 7
 8
 9
10
use SymfonyComponentRoutingAnnotationRoute;

/**
 * @Route("/sum")
 */
public function calculateSum()
{
    $result = $this->sum(5, 3);
    return $this->json(['result' => $result]);
}


  1. Access the route in your browser or through a tool like Postman. For example, if you are using the built-in Symfony web server, you can access the route at http://localhost:8000/sum.
  2. The response should be a JSON object with the sum of the two numbers: {"result": 8}.


That's it! You have successfully used a simple function in Symfony 4. Remember to adapt the code to your specific use case and requirements.
