Laravel 4无法访问select :: db的值

Question

I'm querying DB in laravel 4 but can't access the returned value here is the code :

public static function getCityIdByName($cityname){
    $cityid = DB::select( DB::raw(" SELECT id  FROM cities WHERE match(city_name) against('*" .
        $cityname . "*' IN BOOLEAN MODE ) " ));

    return $cityid;
}

so the function returns this [{"id":1}] and I need to get value "1", I tried $cityid->id and $cityid['id'] and $cityid[0] but it all returns an error , also it is not a string , when I echo it, it complains that array is not a string Array to string conversion

Answer 1

I solved the problem with this code :

return $cityid[0]->id;

thanks to @ Sylwit

Answer 2

Even if it works you can improve it

If you have several results you would take only the first of the array while you would maybe take care of all results.

You can also use ->first() in your query to get only the first object which will avoid you to use the [0].
