What are some best practices for variable naming and code organization in PHP to avoid confusion and errors?

When naming variables in PHP, it is important to use clear and descriptive names that accurately reflect the purpose of the variable. Avoid using ambiguous or overly generic names that could lead to confusion. Additionally, organizing your code into logical sections and using comments to explain complex logic can help prevent errors and make your code more maintainable. 

// Example of clear variable naming and code organization in PHP
$userName = "John Doe";
$userAge = 30;

function greetUser($name, $age) {
    return "Hello, $name! You are $age years old.";
}

echo greetUser($userName, $userAge);
