whereNotIn and when param class type is not same

[mowangjuanzi]

User::whereNotIn("id", function ($builder1) {
        
    })->when(1, function (QueryBuilder $builder2) {
        
    }))

the class type of variable $builder1 is Illuminate\Database\Query\Builder

the class type of variable $builder2 is Illuminate\Database\ Eloquent\Builde

Why can't variables $builder1 and $builder2 be of the same type?

because all query builder that operate on the database, i.e : where, select, etc, is directly operate on the PDO, if you ever use basic query builder using DB facade, that's why the signature is basic query builder.

now all "helpers" method such as when, scope is directly connected with eloquent, thus. eloquent builder is used.

note: since eloquent builder is also instance of basic query builder, all basic query method also implemented.
