What are the potential syntax errors or access violations that can occur when using PDO in PHP?

One potential issue when using PDO in PHP is forgetting to handle exceptions that may occur during database operations. This can lead to uncaught exceptions and potential security vulnerabilities. To solve this, make sure to wrap your PDO code in a try-catch block to handle any exceptions that may arise. 

try {
    $pdo = new PDO($dsn, $username, $password);
    // PDO operations here
} catch (PDOException $e) {
    echo "Connection failed: " . $e->getMessage();
}
