What is PHP?

PHP (Hypertext Preprocessor) is a server-side scripting language created by Rasmus Lerdorf in 1994. Originally designed for web development, it has evolved into a general-purpose language with a rich ecosystem of frameworks and tools. PHP code is executed on the server, and the result is sent to the browser as HTML. Modern PHP (8.x) includes features like named arguments, union types, attributes, fibers, and JIT compilation, making it faster and more expressive than ever.

Key Features

• Server-Side Execution: Code runs on the server, output is sent to the browser.
• Database Integration: Built-in support for MySQL, PostgreSQL, SQLite, and more.
• Large Ecosystem: Thousands of packages via Composer and frameworks like Laravel.
• Easy to Learn: Simple syntax ideal for beginners in web development.
• Cross-Platform: Runs on Windows, macOS, and Linux servers.
