PHP is a powerful and versatile scripting language that offers a wide range of features and capabilities for web development. Its popularity stems from its ease of use, extensive documentation, and large community of developers. PHP is embedded into HTML code, allowing developers to seamlessly integrate logic and data into web pages.
PHP (Hypertext Preprocessor) is a widely-used open-source scripting language specifically designed for web development. It is a server-side scripting language that is executed on the web server before the resulting HTML is sent to the client's web browser. PHP is used to create dynamic and interactive web pages, enabling developers to generate content, connect to databases, and handle user input.
Key Characteristics of PHP:
- Open-source: PHP is freely available for use and modification, making it an accessible and cost-effective choice for web development.
- Server-side scripting: PHP code is executed on the web server, generating dynamic content before being sent to the client's browser.
- Cross-platform compatibility: PHP can run on various operating systems, including Windows, Linux, and macOS.
- Database connectivity: PHP provides extensive support for connecting to various databases, enabling efficient data management and retrieval.
Features of PHP:
PHP offers a comprehensive set of features that cater to various web development needs. Some of its notable features include:
- Dynamic Web Page Creation: PHP enables the creation of dynamic and interactive web pages, allowing developers to generate content based on user input or data from databases.
- Database Connection and Management: PHP provides built-in functions and libraries for connecting to and interacting with various databases, facilitating data storage, retrieval, and manipulation.
