What are the potential pitfalls of using DirectPHP and custom modules in Joomla with different PHP versions?

When using DirectPHP and custom modules in Joomla with different PHP versions, the potential pitfalls include compatibility issues, security vulnerabilities, and performance issues. To solve this problem, make sure to test your code on different PHP versions and update any deprecated functions or syntax to ensure compatibility across all versions. 

// Example code snippet to ensure compatibility with different PHP versions
if (version_compare(PHP_VERSION, '7.0.0', '<')) {
    // Code that is only compatible with PHP versions below 7.0.0
} else {
    // Code that is compatible with PHP versions 7.0.0 and above
}
