In Laravel, you can retrieve the value of a foreign key by using the relationships defined in your models.


For example, if you have a Post model that belongs to a User model, you can access the user's id (foreign key) for a post like this:

1
$user_id = $post->user_id;


You can also use the relationship method to retrieve the related User model and then access the id value:

1
$user_id = $post->user->id;


Make sure you have defined the relationships in your models correctly to access the foreign keys easily.
