Magento 2 - How to Get Configuration Value Programmatically?


2 min read

I wrote this article under Magento 2 version of 2.4.6, latest version might have difference approach.

There are several ways to retrieve system configuration, but there are 2 common approaches, they are using object manager and by injecting into construct method (__construct is the recommended one by Magento itself).

1. by Object Manager

$scopeConfig = \Magento\Framework\App\ObjectManager::getInstance()

$configValue = $scopeConfig->getValue(


  • $scopeConfig = \Magento\Framewo....: we need to define what's the instance / class we want to import / use.

  • $configValue = $scopeCon....: time to retrieve the configuration, further notes will be on 2nd solution below


namespace Fiko\Training\Helper;

class Data
    public $scopeConfig;

    public function __construct(
        \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig
    ) {
        $this->scopeConfig = $scopeConfig;


  • public $scopeConfig;: by the time PHP 8 released, it is mandatory to define the visibility (no dynamic property allowed). it can be public/protected/private, but in this case I would use public as it can be used by other instances.

  • ScopeConfigInterface $scopeConfig: interface we need to have in order to retrieve configuration.

public function getExampleConfig()
    $configValue = $this->scopeConfig->getValue(

    return $configValue;


  • fiko/general/testing_config: it is the path of the configuration.

  • \Magento\Store\Model\ScopeInterface::SCOPE_STORE: It is the scope area (I assume you already know this).

    • I recommend to use SCOPE_STORE, as it will automatically retrieve the higher scope level (website or default) if it doesn't exist on store level.
