PHP Tutorial
PHP is a widely used, open-source server-side scripting language primarily designed for web development. It is embedded directly into HTML and generates dynamic content on web pages, making it essential for building data-driven websites. It allows developers to handle database interactions, session management, and form handling tasks.
- PHP code is executed on the server, generating HTML output sent to the client's browser.
- It is a dynamically typed language, allowing variables to change types during execution, offering flexibility in coding.
- PHP is platform-independent, which means it can run on various operating systems such as Windows, Linux, and macOS.
- PHP supports session management, which allows tracking user activities across different pages on a website.
Note: The latest version, PHP 8.4 (released in 2024), making PHP faster, more efficient, and feature-rich for modern web applications.
