laravel事务

Question

DB::transaction(function () {
    DB::table('users')->update(['votes' => 1]);
    DB::table('posts')->delete();
});

如何传递参数到匿名函数内呢，如果我这样写，报错

DB::transaction(function ($a, $b, $c) {
    DB::table('users')->update(['votes' => 1]);
    DB::table('posts')->delete();
});

Answer 1

DB::transaction(function() use ($a, $b, $c) {
    DB::table('users')->update(['votes' => 1]);
    DB::table('posts')->delete();
});
