How can PHP developers improve readability and maintainability of their code to avoid "spaghetti code" situations?

To improve readability and maintainability of PHP code and avoid "spaghetti code" situations, developers can follow best practices such as using meaningful variable names, breaking down complex tasks into smaller functions, utilizing comments to explain logic, and adhering to a consistent coding style. 

// Example of improved readability and maintainability in PHP code
function calculateTotalPrice($quantity, $price) {
    $total = $quantity * $price;
    return $total;
}

$quantity = 10;
$price = 5.99;
$totalPrice = calculateTotalPrice($quantity, $price);
echo "Total price for $quantity items is: $totalPrice";
