To ensure better code readability and maintainability in PHP, developers can utilize proper formatting techniques such as using BB code or PHP tags. This includes using consistent indentation, commenting code effectively, and following coding standards like PSR-1 and PSR-2. By organizing and structuring code in a clear and standardized manner, developers can make it easier for themselves and others to understand and maintain the codebase.

    return "Hello, $name!";
}

echo greet($name);
