Organizing Collections with Laravel's splitIn Method

Need to split your collection into equal-sized groups? Laravel's new splitIn method makes it a breeze! Let's explore how this handy method helps you organize your data.

Basic Usage

Here's how simple it is:

$collection = collect([1, 2, 3, 4, 5, 6, 7, 8, 9, 10]);
$groups = $collection->splitIn(3);

// Result: [[1, 2, 3, 4], [5, 6, 7, 8], [9, 10]]

Real-World Example

Here's how you might use it in a task distribution system:

class TaskDistributor
{
    public function distributeToTeams(Collection $tasks, int $teamCount)
    {
        $distributedTasks = $tasks->splitIn($teamCount);
        
        return $distributedTasks->map(function ($teamTasks, $index) {
            return [
                'team_number' => $index + 1,
                'task_count' => count($teamTasks),
                'tasks' => $teamTasks->map(fn($task) => [
                    'id' => $task->id,
                    'priority' => $task->priority,
                    'deadline' => $task->deadline->format('Y-m-d')
                ])
            ];
        });
    }
}

// Usage
$tasks = Task::where('status', 'pending')->get();
$distributor = new TaskDistributor();

$teamAssignments = $distributor->distributeToTeams($tasks, 3);

foreach ($teamAssignments as $assignment) {
    $this->info("Team {$assignment['team_number']} received " . 
        "{$assignment['task_count']} tasks");
}

The splitIn method ensures that groups are filled evenly, with any remainder going to the last group. It's perfect for distributing workloads, paginating content, or any scenario where you need balanced groups.
