What are common pitfalls when using PHP to update database records?

One common pitfall when updating database records in PHP is not properly sanitizing user input, which can lead to SQL injection attacks. To mitigate this risk, always use prepared statements with parameterized queries to securely pass user input to the database. 

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

// Update record using prepared statement
$stmt = $pdo->prepare("UPDATE mytable SET column1 = :value1 WHERE id = :id");
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':id', $id);
$stmt->execute();
