Why is it important for PHP beginners to understand the difference between HTML and PHP code?

It is important for PHP beginners to understand the difference between HTML and PHP code because PHP is a server-side scripting language used for dynamic web development, while HTML is a markup language used for creating the structure of web pages. Mixing PHP and HTML code incorrectly can lead to syntax errors and unexpected behavior in the web application. By understanding the distinction between the two languages, beginners can effectively integrate PHP logic into their HTML code to create dynamic and interactive web pages.
