What are some best practices for organizing and structuring PHP scripts to improve code readability and maintainability?

To improve code readability and maintainability in PHP scripts, it is recommended to follow best practices such as using proper indentation, organizing code into logical sections, and using meaningful variable and function names. Additionally, separating concerns by using functions and classes can help make the code more modular and easier to understand.

// Example of organizing and structuring PHP scripts for improved readability and maintainability

// Define functions for different tasks
function calculateTotal($price, $quantity) {
    return $price * $quantity;
}

function displayTotal($total) {
    echo 'Total: $' . $total;
}

// Main script
$price = 10;
$quantity = 5;
$total = calculateTotal($price, $quantity);
displayTotal($total);
