Magento 1.x use Mage::getStoreConfig('sections/groups/fields') get data on core_config_data table.

How to Magento2 get value from core_config_data table ?

We need to call the default method available.

Just Use \Magento\Framework\App\Config\ScopeConfigInterface $scopeConfig, In your constructor argument and set the class property: $this->scopeConfig = $scopeConfig;

Now to Get the configuration value just use

$this->scopeConfig->getValue('dev/debug/template_hints', \Magento\Store\Model\ScopeInterface::SCOPE_STORE);

    good one Meenakshi! keep it up – anshuman Jan 11 '17 at 16:34
  • How do you obtain them from a separate script, not from within the magento filesystem or a module? If you make a class in your script and instantiate it, what should the class inherit from, and how do you ensure it loads all the proper files? – ahnbizcad Jan 18 '18 at 22:19
  • Which scope does this get the configuration from? The currently viewed storeview by the customer? – Erfan Jan 24 '18 at 8:11
  • yes, it'll take current storeview of the customer – MeenakshiSundaram R Jan 24 '18 at 8:13

Create a function for getting configuration values in your custom module's helper.

public function getConfig($config_path)
{
    return $this->scopeConfig->getValue(
            $config_path,
            \Magento\Store\Model\ScopeInterface::SCOPE_STORE
            );
}

and call anywhere you want for example in test.phtml

$moduleStatus = $this->helper('Customvendorname\Custommodulename\Helper\Data')->getConfig('sectionid/groupid/fieldid');

In block and helper call like this:

 $this->_objectManager->create('Customvendorname\Custommodulename\Helper\Data')->getConfig('sectionid/groupid/fieldid');

    It's recommended in M2 to prefer the DI approch. Thus, using $this->_objectManager->create(...) should be avoided. – Anna Völkl Jun 22 '16 at 12:27
  • Thanks @AnnaVölkl, then what is the replacement of that please can you post a similar answer here ? – Manish Jun 22 '16 at 13:12

I have used following method to retrive the variables

if (empty($this->_data['welcome'])) {
        $this->_data['welcome'] = $this->_scopeConfig->getValue(
            'design/header/welcome',
            \Magento\Store\Model\ScopeInterface::SCOPE_STORE
        );
    }
    return $this->_data['welcome'];
