Function returns Null :: laravel

Question

I have a function which gets the value from a database and returns. When I echo, the value does exist. But returned value is null;

public static function getCountryCode($country) {       
    $country = (int) $country;      
    $x = Country::where('id', $country)->get();
    $country_code = '';         
    foreach($x as $row)             
        $country_code = $row->alpha_2;
    //return 'bd';      
    echo $country_code;         
    return $country_code; 
}

Not sure what's wrong in there. It's a laravel project.

Function that is calling this method

public function countryselect()
{
    $country_id = HomeController::detectCountry();
    $country_code = SiteController::getCountryCode($country_id);
    var_dump($country_code);
    return View::make('Layout.countryselect', compact('country_id', 'country_code'));
}

public function countryselect() { $country_id = HomeController::detectCountry(); $country_code = SiteController::getCountryCode($country_id); var_dump($country_code); return View::make('Layout.countryselect', compact('country_id', 'country_code')); } — Ahsan Aasim

It'll be easier to format if you add it to the question. There's a pending edit there though that needs bringing in too. — bcmcfc

You don't have to use "foreach" function. You can get country code in much easier way. Just make some changes in getCountryCode() like

public static function getCountryCode($countryId) {
    $countryId = (int) $countryId;      
    $country = Country::where('id', $countryId)->get()->first();
    return $country->code;
}

This will return the country code of specified country id. Use descriptive name for variable like you used for the function
