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

To optimize PHP code for better readability and maintainability, it is important to follow coding standards, use meaningful variable names, break down complex code into smaller functions, and add comments to explain the code logic. Additionally, organizing code into logical sections and using proper indentation can greatly improve readability. 

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

// Define meaningful variable names
$userName = "John";
$userAge = 30;

// Break down complex logic into smaller functions
function greetUser($name, $age) {
    if ($age < 18) {
        return "Hello, $name! You are under 18.";
    } else {
        return "Hello, $name! You are $age years old.";
    }
}

// Call the function to greet the user
echo greetUser($userName, $userAge);
