How can proper code formatting, such as indentation, improve the readability and maintainability of PHP scripts?

Proper code formatting, such as indentation, improves the readability and maintainability of PHP scripts by making the code structure more organized and easier to follow. Indentation helps to visually separate different code blocks, making it easier to identify the beginning and end of loops, conditionals, and functions. This can greatly reduce the likelihood of errors and make it easier for other developers to understand and modify the code.

php 
<?php

function calculateTotal($price, $quantity) {
    $total = $price * $quantity;
    
    return $total;
}

$price = 10;
$quantity = 5;

$total = calculateTotal($price, $quantity);

echo "Total: $total";

?>
