Are there any best practices for controlling output in PHP?

To control output in PHP, it is recommended to use functions like `htmlspecialchars()` to prevent XSS attacks by escaping special characters in the output. Additionally, using output buffering can help in controlling the order and format of output. Lastly, separating PHP logic from HTML presentation by using templates or frameworks can make it easier to manage output. 

// Example of controlling output using htmlspecialchars()
$userInput = "<script>alert('XSS attack');</script>";
echo htmlspecialchars($userInput);
