What are some best practices for outputting data in PHP to ensure it is displayed as intended?

When outputting data in PHP, it is important to ensure that the data is displayed as intended and to prevent any potential security vulnerabilities. One best practice is to use htmlspecialchars() function to escape special characters and prevent XSS attacks. Additionally, using proper formatting and styling can help improve the readability and presentation of the output data. 

<?php
$data = "<script>alert('XSS attack!')</script>";
echo htmlspecialchars($data, ENT_QUOTES, 'UTF-8');
?>
