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

One common pitfall when updating records in a database using PHP is not properly sanitizing user input, leaving your application vulnerable to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to securely update records in the database. 

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

// Prepare a SQL statement with placeholders
$stmt = $pdo->prepare("UPDATE mytable SET column1 = :value1 WHERE id = :id");

// Bind the parameters and execute the statement
$stmt->bindParam(':value1', $value1);
$stmt->bindParam(':id', $id);
$stmt->execute();
