eloquent take row out of array with relation code example

Example 1: eloquent first

$user = User::where('mobile', Input::get('mobile'))->get();

if (!$user->isEmpty()){
    $firstUser = $user->first()
}

Example 2: laravel model::query

// Eloquent's Model::query() returns the query builder

Model::where()->get();
// Is the same as 
Model::query()->where()->get();

Model::query();
// Can be useful to add query conditions based on certain requirements
