What are common pitfalls when using PHP code in Joomla plugins?

Common pitfalls when using PHP code in Joomla plugins include not properly sanitizing user input, not following Joomla coding standards, and not utilizing Joomla API functions when available. To avoid these issues, always sanitize input data to prevent SQL injection and other security vulnerabilities, adhere to Joomla coding standards for consistency and compatibility with future updates, and make use of Joomla API functions for tasks like database queries or form handling. 

// Example of sanitizing user input in a Joomla plugin
$input = JFactory::getApplication()->input;
$username = $input->get('username', '', 'STRING');
$username = htmlspecialchars($username, ENT_QUOTES, 'UTF-8');
