What are common pitfalls when using PHP for updating multiple database records?

One common pitfall when updating multiple database records in PHP is not using prepared statements, which can leave your application vulnerable to SQL injection attacks. To solve this, always use prepared statements to safely update multiple records in the database. 

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

// Prepare a SQL statement
$stmt = $pdo->prepare('UPDATE table SET column = :value WHERE id = :id');

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