What are some common pitfalls when trying to customize a PHP template?

One common pitfall when customizing a PHP template is not properly escaping user input, which can lead to security vulnerabilities such as cross-site scripting attacks. To solve this issue, always use functions like htmlspecialchars() to escape user input before displaying it on the page. 

// Example of properly escaping user input in a PHP template
$user_input = "<script>alert('Hello!');</script>";
echo htmlspecialchars($user_input);
