Laravel Find Many - PHP

Introduction

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.

Usage

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.
