Are there any potential pitfalls to be aware of when working with templates in PHP?

One potential pitfall when working with templates in PHP is the risk of injection attacks if user input is not properly sanitized before being inserted into the template. To prevent this, always use proper escaping functions like htmlspecialchars() to ensure that user input is displayed safely. 

// Example of using htmlspecialchars() to escape user input before inserting into a template
$user_input = "<script>alert('XSS attack!')</script>";
$safe_input = htmlspecialchars($user_input, ENT_QUOTES, 'UTF-8');
echo "<p>User input: $safe_input</p>";
