php-laravelHow can I create a relationship between two models in Laravel using PHP?

Creating a relationship between two models in Laravel using PHP is done through Eloquent ORM. Eloquent ORM provides a simple ActiveRecord implementation for working with the database. The following example illustrates how to create a relationship between two models in Laravel using PHP:

// Model A
class User extends Model
{
    public function posts()
    {
        return $this->hasMany('App\Post');
    }
}

// Model B
class Post extends Model
{
    public function user()
    {
        return $this->belongsTo('App\User');
    }
}

In the example, the User model has a posts method which defines a one-to-many relationship with the Post model. The Post model has a user method which defines a one-to-one relationship with the User model.

The following parts explain the example code:

• User model: defines a one-to-many relationship with the Post model.
• posts method: defines a one-to-many relationship.
• Post model: defines a one-to-one relationship with the User model.
• user method: defines a one-to-one relationship.
