How can PHP developers effectively separate content and functionality by distributing functions and HTML across different files in a project?

To effectively separate content and functionality in a PHP project, developers can distribute functions and HTML across different files. One common approach is to create separate files for functions (e.g., functions.php) and HTML templates (e.g., header.php, footer.php). By doing this, developers can keep the logic and presentation layers separate, making the code more organized and easier to maintain. 

// functions.php
function calculateTotal($price, $quantity) {
    return $price * $quantity;
}

// header.php
<!DOCTYPE html>
<html>
<head>
    <title>My Website</title>
</head>
<body>

// footer.php
</body>
</html>

// index.php
include 'functions.php';
include 'header.php';

$price = 10;
$quantity = 5;
$total = calculateTotal($price, $quantity);
echo "Total: $" . $total;

include 'footer.php';
