{
    public function get(
        string $key,
        string $delimiter = null,
        bool $ignoreNotFound = false
    ): array|bool|string|int|float|UnitEnum|null;

    public function getString(string $key, string $delimiter = null): string;
    public function getInt(string $key, string $delimiter = null): int;
    public function getFloat(string $key, string $delimiter = null): float;
    public function getBoolean(string $key, string $delimiter = null): bool;
    public function getArray(string $key, string $delimiter = null): array;
    public function getUnitEnum(string $key, string $delimiter = null): UnitEnum;
    public function has(string $key, string $delimiter = null): bool;
}

Project parameters.

# config/services.yaml

parameters:
  locale: 'en'
  debug: false
  price: 200.00

    analytics_code: 'UA-X000000'

3.1 Service

Get parameters in controller.

<?php declare(strict_types=1);

namespace App\Controller;

use Danilovl\ParameterBundle\Interfaces\ParameterServiceInterface;
use Knp\Component\Pager\Pagination\PaginationInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;

class BaseController extends AbstractController
{
    protected function createPagination(
        Request $request,
        $query,
        int $page = null,
        int $limit = null,
        array $options = null
    ): PaginationInterface {
        $page = $page ?? $this->get(ParameterServiceInterface::class)
                ->getInt('pagination::default::page', '::');

        $limit = $limit ?? $this->get(ParameterServiceInterface::class)
                ->getInt('pagination.default.limit');

        $pagination = $this->get('knp_paginator');
        if ($options !== null) {
            $pagination->setDefaultPaginatorOptions($options);
        }

        return $pagination->paginate(
            $query,
            $request->query->getInt('page', $page),
            $request->query->getInt('limit', $limit)
        );
    }
}

Get parameters by DI.

<?php declare(strict_types=1);

namespace App\Service;

use Knp\Component\Pager\Pagination\PaginationInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Danilovl\ParameterBundle\Interfaces\ParameterServiceInterface;

class UserService
{
    public function __construct(private ParameterServiceInterface $parameterService)
    {
    }
    
    public function getUserRoles(): array
    {
        return $this->parameterService->getArray('user.roles');
    }
}

Ignore ParameterNotFoundException if parameter not exist. Method get return null.

<?php declare(strict_types=1);

namespace App\Service;

use Knp\Component\Pager\Pagination\PaginationInterface;
use Symfony\Bundle\FrameworkBundle\Controller\AbstractController;
use Symfony\Component\HttpFoundation\Request;
use Danilovl\ParameterBundle\Interfaces\ParameterServiceInterface;

class WidgetService
{
    public function __construct(private ParameterServiceInterface $parameterService)
    {
    }
    
    public function getWidgetName(): string
    {
        return $this->parameterService->get(key: 'widget.name', ignoreNotFound: true) ?? 'default widget name';
    }
}

3.2 Twig extension

Check debug parameter in templates.

{# templates/first.html.twig #}

{% if parameter_has('debug') == true %}
    {#some code#}
{% endif %}

{% if parameter_get_string('locale') == 'en' %}
    {#some code#}
{% endif %}

Get google api parameters.

{# templates/first.html.twig #}

{{ parameter_get('google.api_key') }}

{{ parameter_get_string('google.api_key') }}
{{ parameter_get_string('google.analytics_code') }}
