What are some common pitfalls when updating multiple records in a PHP application's database?

One common pitfall when updating multiple records in a PHP application's database is not using prepared statements, which can lead to SQL injection attacks. To avoid this, always use prepared statements to securely update multiple records in the database. 

// Connect to the database
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare the update statement
$stmt = $pdo->prepare("UPDATE mytable SET column1 = :value1 WHERE id = :id");

// Iterate through the records to update
foreach ($records as $record) {
    // Bind the parameters and execute the statement
    $stmt->bindParam(':value1', $record['value1']);
    $stmt->bindParam(':id', $record['id']);
    $stmt->execute();
}
