Store all phone numbers in one table

This is a good idea and it can be implemented in a few different ways. One way is to create a phone_numbers table with the following columns:

• id: Primary key
• model_name: The name of the model that owns the phone number
• model_id: The ID of the model that owns the phone number
• phone_number: The phone number

Then, you can create a relationship between the phone_numbers table and the other models that need to store phone numbers. For example, if you have a User model, you can create a one-to-many relationship between the User model and the phone_numbers table.

class User extends Model
{
    public function phoneNumbers()
    {
        return $this->hasMany(PhoneNumber::class);
    }
}

class PhoneNumber extends Model
{
    public function user()
    {
        return $this->belongsTo(User::class);
    }
}

You can then use Eloquent to create, update, and delete phone numbers for a user.

$user = User::find(1);

// Create a new phone number
$user->phoneNumbers()->create([
    'phone_number' => '123-456-7890',
]);

// Update an existing phone number
$phoneNumber = $user->phoneNumbers()->first();
$phoneNumber->update([
    'phone_number' => '098-765-4321',
]);

// Delete an existing phone number
$phoneNumber = $user->phoneNumbers()->first();
$phoneNumber->delete();

This approach can be used for any model that needs to store phone numbers, emails, or addresses.
