How can readability and clarity be improved when writing code for passing variables in PHP?

To improve readability and clarity when passing variables in PHP, it is helpful to use meaningful variable names and properly format the code. Additionally, using comments to explain the purpose of each variable can make the code more understandable for others who may need to work on it in the future. 

// Example of passing variables with meaningful names and comments
$userName = "John Doe"; // Store the user's name
$userAge = 25; // Store the user's age
echo "User: $userName, Age: $userAge"; // Output the user's information
