Roadmap to Learn PHP
Introduction to PHP
PHP (Hypertext Preprocessor) is a widely-used open-source general-purpose scripting language that is especially suited for web development. It can be embedded into HTML.
PHP is executed on the server, and the result is returned to the browser as plain HTML. This means users cannot view the PHP code itself.
Key features of PHP include:
- Server-side scripting
- Cross-platform compatibility
- Database support
- Large community and extensive libraries
- Relatively easy to learn
