PHP (Hypertext Preprocessor) is an open-source, server-side scripting language used for web development. It was originally created in 1994 by Rasmus Lerdorf and has since become one of the most popular programming languages for web development.
Some key features of PHP include:
- Open-Source: PHP is free to use and distribute, and its source code is available for modification and enhancement by developers around the world.
- Cross-Platform: PHP can be run on various operating systems, including Windows, Mac OS, Linux, and Unix.
- Server-Side Scripting: PHP code is executed on the server-side, which means that it is processed on the server before the result is sent to the client’s web browser.
- Embedded in HTML: PHP can be embedded in HTML code, which allows developers to create dynamic web pages that can interact with databases, handle forms, and perform other tasks.
- Supports Various Databases: PHP supports several databases, including MySQL, PostgreSQL, Oracle, and Microsoft SQL Server.
- Easy to Learn: PHP has a simple syntax that is easy to learn, making it a good choice for beginners in web development.
- Large Community: PHP has a large and active community of developers who contribute to its development and share their knowledge and expertise through forums, blogs, and other online resources.
PHP is commonly used for building dynamic websites and web applications, such as blogs, e-commerce sites, social networks, and content management systems. It can also be used for server-side scripting, command-line scripting, and GUI applications.
PHP was introduced by Rasmus Lerdorf in 1994.
