What potential pitfalls should be avoided when using a two-dimensional array to update database records in PHP?

One potential pitfall to avoid when using a two-dimensional array to update database records in PHP is not properly sanitizing user input. This can leave your application vulnerable to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to securely update database records. 

// Assuming $data is a two-dimensional array containing the records to be updated

// Establish a database connection
$pdo = new PDO("mysql:host=localhost;dbname=mydatabase", "username", "password");

// Prepare a statement
$stmt = $pdo->prepare("UPDATE mytable SET column1 = :value1, column2 = :value2 WHERE id = :id");

// Loop through the data array and execute the statement for each record
foreach ($data as $record) {
    $stmt->execute([
        'value1' => $record['value1'],
        'value2' => $record['value2'],
        'id' => $record['id']
    ]);
}
