What are some common pitfalls to avoid when working with PHP to update database records?

One common pitfall to avoid when working with PHP to update database records is not sanitizing user input, which can leave your application vulnerable to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to securely update database records. 

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

// Prepare a SQL statement with a parameterized query to update a record
$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();
