Access to out-of-scope variable within anonymous functions in Laravel (PHP)

Question

I want to seed the related tables in Laravel. I had a problem in access to the out-of-scope variable inside the anonymous function which I had defined for whereHas methods to put "where" conditions on my has queries.

$id = $user->id; // out-of-scope variable
$posts = Post::whereHas('comments', function ($query) {
    $query->where('user_id', $id);
})->get();

Technically I don't have access to $id inside the anonymous function.

This isn't a Laravel question, but a PHP one. Just add use ($variable) after the parameter list:

$posts = Post::whereHas('comments', function ($query) use ($id) {
    $query->where('user_id', $id);
})->get();
