ExcessiveMethodLength

Emitted when a method has too many lines of code, making it hard to understand and maintain.

<?php
public function processOrder(array $data): array
{
    // Line 1-10: Validate input
    // Line 11-30: Process payment
    // Line 31-50: Update inventory
    // Line 51-70: Send notifications
    // Line 71-90: Generate reports
    // Line 91-100: Cleanup
    // ... 100+ lines of code
}

Why this is bad

Hard to understand: Too much logic in one place
Hard to test: Need complex setup to cover all paths
Hard to reuse: Logic is tightly coupled
Hard to maintain: Changes risk breaking unrelated code

How to fix

Extract logical sections into separate methods:

<?php
public function processOrder(array $data): array
{
    $this->validateInput($data);
    $payment = $this->processPayment($data);
    $this->updateInventory($data);
    $this->sendNotifications($data);

    return $this->generateResult($payment);
}

private function validateInput(array $data): void
{
    // Focused validation logic
}

private function processPayment(array $data): Payment
{
    // Focused payment logic
}
