What are best practices for integrating PHP code into an existing HTML website?

When integrating PHP code into an existing HTML website, it is best practice to separate the PHP code from the HTML markup by using PHP opening and closing tags. This allows for better organization and maintenance of the code. Additionally, make sure to sanitize user input to prevent security vulnerabilities such as SQL injection.
