What are the common pitfalls in updating database records in PHP using PDO, and how can they be avoided?

One common pitfall in updating database records in PHP using PDO is not properly binding parameters in the query, which can leave the application vulnerable to SQL injection attacks. To avoid this, always use prepared statements and bind parameters securely. 

// Update database record using PDO with prepared statements and parameter binding

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

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

// Bind parameters securely
$stmt->bindParam(':value1', $value1, PDO::PARAM_STR);
$stmt->bindParam(':id', $id, PDO::PARAM_INT);

// Set parameter values
$value1 = "new value";
$id = 1;

// Execute query
$stmt->execute();
