Utilize online resources, tutorials, and books dedicated to PHP. Practice by creating small, simple applications before tackling larger projects.

Is it necessary to know HTML and CSS before learning PHP?

While it’s possible to learn PHP without prior knowledge of HTML and CSS, having a basic understanding of these languages is highly beneficial. Since PHP is often used to generate HTML content, knowing HTML and CSS will make it easier to understand how PHP fits into the development of web pages and applications.
