In Laravel, the findMany
method allows you to retrieve multiple records from a database table based on an array of primary keys. This method provides a convenient way to fetch multiple records in a single query, improving performance and reducing database overhead.
The findMany
method can be called on the Eloquent model class or on a query builder instance. It accepts an array of primary key values as its argument and returns a collection of model instances representing the retrieved records.
Here is an example of using findMany
to retrieve multiple records from a users
table:
$users = User::findMany([1, 2, 3]);
In this example, the findMany
method retrieves the records with primary keys 1, 2, and 3 from the users
table and returns a collection of User
model instances.
