Laravel从交易中返回价值

Question

I'm working with transactions in laravel 5, so far I have been getting the results of any method outside of the statement with a reference param &$, but I red this is a bad practice because the operator "&" is obsolete. Is there any other way to get the value of a var outside transaction scope?

this is a code example:

public function post(Request $request, Persona $persona)
{
    try {
        DB::transaction(function () use ($request, &$result) {          
            $result = Persona::create($request->all());
            // ... Moooore code omitted 
        });

        // Do more thing with $result 
        $result;
    } // ...
}}

Use DB::beginTransaction() and DB::commit() instead:

DB::beginTransaction();
try {
    $result = Persona::create($request->all());
    DB::commit();
} catch (Exception $e) {
    DB::rollBack();
}
