Memory Issue Detection

Analyze PHP code for memory usage problems.

Detection Patterns

1. Large Arrays in Memory

// MEMORY HOG: Loading entire table
$users = $repository->findAll(); // 1M users = OOM
foreach ($users as $user) {
    process($user);
}

// MEMORY HOG: Building large array
$data = [];
foreach ($hugeDataset as $item) {
    $data[] = transform($item); // Array grows unbounded
