What are some common pitfalls or mistakes to avoid when dealing with transactions and multiple insert statements in PHP PDO?

One common pitfall when dealing with transactions and multiple insert statements in PHP PDO is not properly handling errors and rolling back the transaction if an error occurs. To avoid this, make sure to set PDO error mode to PDO::ERRMODE_EXCEPTION and wrap your insert statements in a try-catch block to catch any exceptions. 

try {
    $pdo->beginTransaction();

    // Insert statement 1
    $stmt = $pdo->prepare("INSERT INTO table1 (column1) VALUES (:value1)");
    $stmt->bindParam(':value1', $value1);
    $stmt->execute();

    // Insert statement 2
    $stmt = $pdo->prepare("INSERT INTO table2 (column2) VALUES (:value2)");
    $stmt->bindParam(':value2', $value2);
    $stmt->execute();

    $pdo->commit();
} catch (PDOException $e) {
    $pdo->rollBack();
    echo "Error: " . $e->getMessage();
}
