What are some common pitfalls to avoid when using PHP template systems?

One common pitfall to avoid when using PHP template systems is mixing logic with presentation. It is important to keep your templates clean and focused on displaying data, while moving any logic or calculations to the PHP files. This will make your code more maintainable and easier to read. 

// Bad practice: mixing logic with presentation in template
<div>
    <?php 
    $total = $price * $quantity; 
    echo "Total price: $" . $total; 
    ?>
</div>

// Good practice: moving logic to PHP file
<?php 
$total = $price * $quantity; 
?>
<div>
    Total price: $<?php echo $total; ?>
</div>
