PHP: What It Is and Its History
PHP (Hypertext Preprocessor) is an open-source scripting language used for web development. Created in 1995 by Rasmus Lerdorf, PHP is widely used to create dynamic and interactive websites. Initially named “Personal Home Page Tools,” PHP has evolved over time to become one of the preferred languages for developing complex web applications.
What Can Be Done with PHP?
- Developing web pages and applications
- Creating server-side scripts
- Database management
- User login and session management
- E-commerce sites
- CMS systems (like WordPress)
- APIs and web services
- Data analysis and reporting
The Difference Between Interpreted and Compiled Programming Languages
Programming languages are generally divided into two categories: interpreted and compiled. In compiled languages (e.g., C++), code is first translated into machine language and then executed, typically offering faster performance. In interpreted languages (e.g., PHP), code is processed directly, line by line, which simplifies the development process but may reduce performance.
