How can PHP code be optimized for better readability and maintainability?

To optimize PHP code for better readability and maintainability, you can follow best practices such as using meaningful variable names, breaking down complex code into smaller functions, using comments to explain logic, and following a consistent coding style. 

// Example of optimized PHP code for better readability and maintainability

// Using meaningful variable names
$userName = "John Doe";
$age = 30;

// Breaking down complex code into smaller functions
function calculateTotal($price, $quantity) {
    return $price * $quantity;
}

// Using comments to explain logic
// Get user details from database
$userDetails = getUserDetails($userId);

// Following a consistent coding style
if ($userDetails['age'] >= 18) {
    echo "User is an adult.";
} else {
    echo "User is a minor.";
}
