Batch Processing Analysis

Analyze PHP code for batch processing opportunities.

Detection Patterns

1. Single-Item vs Bulk Operations

// SLOW: Individual inserts
foreach ($users as $user) {
    $pdo->query("INSERT INTO users (name, email) VALUES ('$name', '$email')");
}

// FAST: Bulk insert
$values = [];
$params = [];
foreach ($users as $i => $user) {
    $values[] = "(:name{$i}, :email{$i})";
