Laravel first or new
In Laravel, first()
and new()
are two different methods that serve distinct purposes.
first()
:
first()
is a method on Eloquent query builders that returns the first record that matches the query. It's often used to retrieve a single record from a database table. For example:
$user = User::where('email', '[email protected]')->first();
This code will retrieve the first user record with the email [email protected]
and assign it to the $user
variable.
new()
:
new()
is a PHP constructor that creates a new instance of a class. In Laravel, you can use new
to create a new instance of an Eloquent model, such as a User
model:
$user = new User();
This code will create a new, empty User
model instance and assign it to the $user
variable.
When to use each:
- Use
first()
when you need to retrieve a single record from a database table. - Use
new()
when you need to create a new instance of an Eloquent model, such as when you're creating a new record in the database.
In summary:
first()
retrieves a single record from a database table.new()
creates a new instance of an Eloquent model.
