php – 如何使用laravel 4.2中的两个值检查一个字段

$input = Input::all();


$user = User::where(function($q) {
          $q->where('email', $input['email'] )
            ->orWhere('email', $input['emails'][0]['value'] );
      })
      ->first();

   print_r($user);die;

总是说Undefined变量：输入
        比较电子邮件与两个值的最佳方法是什么,请指导

解决方法:

添加use($input)将$input变量传递给闭包范围：

User::where(function ($q) use ($input) {

Closures may also inherit variables from the parent scope. Any such variables must be passed to the use language construct.
