What are the potential pitfalls of using a tool that generates messy PHP code like this?

Using a tool that generates messy PHP code can lead to readability issues, maintenance difficulties, and potential bugs in the code. To solve this problem, it's important to manually clean up the generated code, refactor it for better structure and readability, and ensure that it follows best practices for PHP coding standards.

// Example of refactored and cleaned up PHP code
function calculateTotal($price, $quantity) {
    $total = $price * $quantity;
    return $total;
}
$total = calculateTotal(10, 5);
echo "Total: $total";
