What are common pitfalls when updating database entries in PHP applications?

One common pitfall when updating database entries in PHP applications is not properly sanitizing user input, which can lead to SQL injection attacks. To prevent this, always use prepared statements with parameterized queries to securely update database entries. 

// Update database entry using prepared statements
$stmt = $pdo->prepare("UPDATE table_name SET column_name = :value WHERE id = :id");
$stmt->bindParam(':value', $value);
$stmt->bindParam(':id', $id);
$stmt->execute();
