What are some best practices for incorporating PHP variables into CSS styles within templates?

When incorporating PHP variables into CSS styles within templates, it is important to properly escape and sanitize the variables to prevent security vulnerabilities like XSS attacks. One common approach is to use inline styles or inline CSS within the HTML template and dynamically set the styles using PHP variables. 

<?php
// PHP variable
$color = "#FF0000";
?>

<!DOCTYPE html>
<html>
<head>
    <style>
        .custom-div {
            color: <?php echo htmlspecialchars($color); ?>;
        }
    </style>
</head>
<body>
    <div class="custom-div">This text will be styled with the color from the PHP variable</div>
</body>
</html>
